Gerunds vs. Participles: Understanding -ing Words

Both gerunds and present participles are verb forms that end in -ing, but they perform fundamentally different jobs in a sentence. While they look identical on the surface, their grammatical role determines whether they act as nouns, active verbs, or adjectives.

What Is a Gerund?

A gerund is an -ing verb form that functions as a noun (as a subject, object, or complement).

“Swimming is my favourite hobby.”
➔ Subject noun of the sentence.
What Is a Participle?

A participle is a verb form that works as a descriptive adjective or as part of a continuous verb phrase.

“The boy is swimming.” / “The crying baby needs milk.”
➔ Verb tense component & adjective modifier.

Same Word, Different Functions

Words like swimming and crying derive from verbs, but their role depends entirely on sentence context:

• Noun Role: “Swimming improves cardiovascular health.” ➔ Gerund
• Active Verb Role: “The boy is swimming across the pool.” ➔ Present Participle
• Adjective Role: “We soothed the crying baby.” ➔ Participial Adjective

Quick Comparison Table

Grammatical Form Sentence Function Example Sentence
Gerund Acts as a Noun (Subject or Object) Swimming is my favourite hobby.
Participle (Verb) Forms a Continuous Tense with “be” The boy is swimming.
Participle (Adjective) Modifies and describes a Noun The crying baby needs milk.

Quick Challenge

In which of the following sentences does the word “swimming” function as a gerund? Tap your answer.

See the full explanation

Answer: “Swimming is my favourite hobby.”

Function breakdown:

  • Gerund Role: In “Swimming is my favourite hobby,” swimming answers “What is my favourite hobby?” and serves as the subject noun.
  • Participle Role: In “The boy is swimming,” swimming describes an action currently underway in a continuous tense.
  • Key Test: If you can replace the -ing word with a regular noun (e.g., “Chess is my favourite hobby”) and the grammar remains intact, it is a gerund.

How Are Gerunds Formed?

A gerund is formed by attaching -ing to a base verb (read ➔ reading, play ➔ playing, cook ➔ cooking). Because gerunds share the exact same spelling rules as present participles, standard adjustments apply when adding the suffix.

1. Drop the Silent “e”

Remove the final e before adding -ing:

  • make ➔ making | write ➔ writing
  • dance ➔ dancing | ride ➔ riding
2. Double the Final Consonant

Short C-V-C verbs double the final consonant:

  • run ➔ running | sit ➔ sitting
  • swim ➔ swimming | stop ➔ stopping
3. Change “ie” to “y”

Verbs ending in -ie change to y before adding -ing:

lie ➔ lying  |  tie ➔ tying  |  die ➔ dying

How Are Gerunds Used in Sentences?

Because a gerund functions as a noun, it can take on any grammatical role that a standard noun performs:

1. Sentence Subject
“Reading improves vocabulary.”

Acts as the topic noun of the sentence.

2. Verb Object
“I enjoy reading.”

Receives the action of verbs like enjoy, finish.

3. Object of Preposition
“He left without saying goodbye.”

Always follow prepositions with -ing.

4. Subject Complement
“My hobby is painting.”

Follows linking verbs (is, was) to rename the subject.

Deep Dive: Gerunds as Subjects & Gerund Phrases

When placed at the beginning of a clause, a gerund replaces a noun subject entirely:

• Noun Subject: “Football is enjoyable.”
• Gerund Subject: “Swimming is enjoyable.”

Gerunds can also take their own objects, creating a gerund phrase that acts as the complete subject:

  • “Reading books helps children learn.”
  • “Playing outside is good for health.”
  • “Learning new words improves your English.”
  • “Reading English books every day improves vocabulary.” (The entire phrase is the subject).

Gerunds as Direct Objects

Certain English verbs are followed exclusively or commonly by a gerund rather than an infinitive:

enjoy avoid finish practise keep suggest dislike love like
  • She enjoys reading books.
  • She finished cleaning her room.
  • We practise speaking English every day.
  • They avoid making noise in the library.

Gerunds After Prepositions: The Golden Rule

The Preposition Rule:

Whenever a verb comes immediately after a preposition (in, on, at, about, without, by, before, after, of, for), it must take the -ing gerund form.

❌ Incorrect: “She left without to say goodbye.”
✅ Correct: “She left without saying goodbye.”
  • She is interested in learning English.
  • We talked about going to the park.
  • He improved his skills by reading books.
  • Wash your hands before eating.
  • He learned English by practising every day.

Quick Challenge

Which of the following sentences correctly applies a gerund after a preposition with proper spelling? Tap your answer.

See the full explanation

Answer: “He improved his English fluency by practising every day.”

Grammar breakdown:

  • Preposition Rule: After prepositions like by, without, in, about, and before, verbs must take the -ing (gerund) form.
  • Gerund Role: practising acts as the object of the preposition by.
  • Spelling Checks: swim ➔ swimming (double consonant), make ➔ making (drop e), lie ➔ lying (ie ➔ y).

Understanding Gerund Phrases

A gerund phrase begins with a gerund (an -ing verb form) and includes its accompanying objects, modifiers, or prepositional phrases. The entire phrase functions collectively as a single noun.

Analyzing a Gerund Phrase:
• “Reading books before bedtime is relaxing.”
Gerund: reading ➔ Complete Gerund Phrase (Subject Noun): Reading books before bedtime
  • Playing football with my friends is enjoyable. (Subject phrase).
  • I enjoy watching cartoons after school. (Object phrase).
  • Learning new English words takes practice. (Subject phrase).
  • Learning English every day improves your skills.

What Are Participles?

A participle is a verb form that functions as an adjective, creates continuous or perfect verb tenses, or introduces participial modifier clauses. English has two primary participle types:

1. Present Participles (-ing)
  • Continuous Tenses: “She is singing.” / “The boy is running.”
  • Noun Modifiers: “The singing girl is my sister.”
  • Introductory Phrases: “Running quickly, Ali caught the bus.”
2. Past Participles (V3)
  • Perfect Tenses: “She has written a letter.”
  • Passive Voice: “The window was broken.”
  • Participial Adjectives: “He sat on a broken chair.”

Gerund vs. Present Participle

Because both gerunds and present participles end in -ing, the surface spelling never reveals the word’s grammatical identity. The distinction lies entirely in functional behavior:

Gerund = Acts as a Noun
• “Swimming is fun.” (Subject)
• “I enjoy swimming.” (Direct Object)
• “Reading is my favorite hobby.” (Subject)
Participle = Verb / Adjective
• “Ali is swimming.” (Verb Phrase)
• “The swimming boy waved.” (Adjective)
• “Sara is reading a book.” (Verb Phrase)
The 3-Second Identification Test:
  • Is it acting like a noun (Subject/Object)? ➔ Gerund
  • Is it pairing with “be” to show ongoing action? ➔ Present Participle
  • Is it directly describing a noun? ➔ Present Participle (Adjective)

Side-by-Side Comparison Chart

Gerund (Noun Function) Present Participle (Verb / Adjective)
Swimming is fun. Ali is swimming.
I enjoy reading. The crying baby needs milk.
Playing is enjoyable. The children are playing.
Learning English is useful. The learning students worked hard.
Swimming is good exercise. The children are swimming.

3 Steps to Identify an -ing Word

Follow this systematic process whenever diagnosing ambiguous -ing words in reading and grammar exams:

Step 1
Locate the -ing Word

Isolate the word ending in -ing within the clause (e.g., “Ali is playing football” or “Playing is fun”).

Step 2
Examine Its Grammatical Role

Ask: Is it the subject/object of the sentence (Gerund), forming a continuous verb with is/are/was/were (Participle), or describing a noun (Participle)?

Step 3
Evaluate the Sentence in Context

Never identify an -ing word in isolation. Always review the full clause structure to verify its relationship with neighboring words.

Quick Challenge

In the sentence “I enjoy reading historical books in the library,” what is the grammatical classification of the word “reading”? Tap your answer.

See the full explanation

Answer: A. Gerund

Grammar breakdown:

  • Noun Function: In “I enjoy reading historical books,” reading historical books is a gerund phrase serving as the direct object of the verb enjoy.
  • Substitution Test: Replace reading with a standard noun (e.g., “I enjoy literature”)—the sentence structure remains identical.
  • Contrast: In “Sara is reading historical books,” reading pairs with is to form a present continuous verb phrase (Present Participle).

Gerunds and Participles in the Same Sentence

A single sentence can easily feature both a present participle and a gerund. Because both share the -ing suffix, you must analyze the functional job of each individual word rather than assuming they perform identical roles.

Case Study 1: “Walking home, Ali enjoys listening to music.”
Walking
Present Participle: Begins an introductory participial phrase describing Ali’s ongoing activity while moving.
listening
Gerund (Noun): Acts as the direct object noun of the verb enjoys (Ali enjoys what? ➔ listening to music).
Case Study 2: “Reading quietly, Sara enjoys learning new words.”
Reading
Present Participle: Modifies the subject (Sara) by detailing how she is situated.
learning
Gerund (Noun): Functions as the direct object of the transitive verb enjoys.

Participial Phrases (Present vs. Past)

A participial phrase begins with a participle and adds descriptive background about a nearby noun or pronoun without requiring a separate sentence.

Present Participle Phrases (-ing)
  • “Running quickly, Ali caught the bus.” (Describes Ali).
  • “Smiling happily, Sara opened the gift.” (Describes Sara).
  • “Holding an umbrella, Tom walked home.” (Describes Tom).
Past Participle Phrases (V3)
  • “Tired after the game, the players sat down.” (Describes the players’ state).
  • “Exhausted from the climb, the hikers rested.”
  • “Damaged by the wind, the roof was repaired.”

Avoiding Dangling Participles

Core Modifier Placement Rule:

The noun or pronoun placed immediately after the comma must be the actual person or object performing the participial action. If an unrelated subject is placed there, the modifier “dangles” and creates an unintentional, illogical meaning.

❌ Dangling: “Walking to school, the bus passed Ali.”
(Makes it sound as though the school bus was walking on foot).
✅ Corrected: “Walking to school, Ali saw the bus.”
(Places Ali immediately after the comma as the entity walking).
❌ Dangling: “Looking through the window, the mountain looked beautiful.”
✅ Corrected: “Looking through the window, I saw a beautiful mountain.”

Quick Challenge

Which of the following sentences correctly avoids a dangling participle and accurately links the introductory phrase to the proper subject? Tap your answer.

See the full explanation

Answer: “Walking home from school, Sara got caught in the sudden rain.”

Grammar and modifier analysis:

  • Modifier Subject Match: Walking home from school is an introductory participial phrase modifying Sara, who follows directly after the comma.
  • Dual -ing Sentences: In sentences like “Running to school, Ali enjoys listening to music,” Running is a present participle modifying Ali, while listening is a gerund acting as the noun object of enjoys.
  • Dangling Participle Prevention: Always confirm that the noun directly following your introductory comma is the true actor performing the participle’s action.

Present Participles and Continuous Tenses

Every continuous (progressive) tense in English requires a present participle (-ing form) paired with an appropriate auxiliary form of be.

Form of “Be” + Verb-ing
Present Continuous

Action happening right now.

“She is reading.”
Past Continuous

Action underway at a past time.

“She was reading.”
Future Continuous

Action in progress in the future.

“She will be reading.”
Perfect Continuous

Ongoing duration up to a point.

“She has been reading.”

Gerunds vs. Infinitives After Verbs

When connecting two verbs together, certain main verbs require a gerund (-ing), while others demand an infinitive (to + base verb):

Followed by Gerunds (-ing)

Common verb patterns taking -ing nouns:

enjoy reading avoid running finish eating practise speaking
• “I enjoy reading books.”
Followed by Infinitives (to + Verb)

Common verb patterns taking to + base form:

want to read need to study hope to win decide to go
• “I want to read books.”
Avoiding Common Verb Pattern Errors:
❌ Incorrect: “I enjoy to read books.”
✅ Correct: “I enjoy reading books.” (The verb enjoy must be followed by a gerund).
Learning Tip: Instead of memorizing abstract grammatical categories, learn verbs together with their natural companion pattern as complete phrases (e.g., “enjoy doing,” “avoid making,” “want to go,” “need to study”).

Quick Challenge

Which of the following sentences correctly applies a gerund after a verb of preference and correctly identifies a present participle in a past continuous tense? Tap your answer.

See the full explanation

Answer: “I enjoy reading novels while the children were playing football outside.”

Grammar breakdown:

  • Gerund After “Enjoy”: enjoy is always followed by a gerund noun ➔ enjoy reading.
  • Past Continuous Participle: In “were playing,” playing is the present participle functioning with were to show ongoing past action.
  • Verb Pattern Reference:
    • Gerund: enjoy, avoid, finish, practise ➔ + verb-ing
    • Infinitive: want, need, hope, decide ➔ + to-infinitive

Gerunds After Common Expressions

Many set idiomatic expressions in English naturally pair with a gerund (-ing form) rather than an infinitive. Learning these patterns as complete phrases guarantees accurate sentence construction.

be busy + -ing have difficulty + -ing have fun + -ing be worth + -ing spend time + -ing there is no point in + -ing
  • Sara is busy doing her homework.
  • I had difficulty understanding the question.
  • We had fun playing football.
  • This book is worth reading.
  • Alina spends a lot of time drawing.
  • There is no point in arguing about it.
Avoiding Infinitive Substitution:
❌ Incorrect: I had difficulty to understand the lesson.
✅ Correct: I had difficulty understanding the lesson.

Participles in Compound Adjectives

A present participle can unite with an adverb, adjective, or noun to create a compound adjective that modifies a following noun:

Common Compound Examples
  • a hard-working student
  • a good-looking building
  • a fast-moving train
  • a long-lasting battery
  • an English-speaking country
Hyphenation & Syntax

When the compound adjective precedes the noun it modifies, use a hyphen to join the words into a single descriptive unit:

• “She is a hard-working student.” (Compound Adjective)
• “She works hard.” (Verb + Adverb)

Using Participles to Streamline Sentences

Participial phrases can replace longer coordinate or subordinate clauses, producing smoother, more concise writing:

Full Compound / Subordinate Clause Concise Participial Phrase
Ali was walking to school, and he saw his teacher. Walking to school, Ali saw his teacher.
Sara was smiling as she opened the present. Smiling, Sara opened the present.
Because he felt tired, Ahmed went to bed. Feeling tired, Ahmed went to bed.
Because Sara felt happy, she smiled at her friends. Feeling happy, Sara smiled at her friends.
Clarity Rule: When condensing clauses, ensure the entity performing the action in the introductory participial phrase is the exact same subject positioned immediately after the comma.

Quick Challenge

Which sentence correctly condenses “Because Sara felt happy, she smiled at her friends” into a concise participial phrase while maintaining clear subject alignment? Tap your answer.

See the full explanation

Answer: “Feeling happy, Sara smiled at her friends.”

Grammar breakdown:

  • Reason Reduction: “Because Sara felt happy” streamlines cleanly into the present participle phrase “Feeling happy”.
  • Subject Consistency: Placing Sara immediately after the comma preserves logical agency (Sara feels happy and performs the smile).
  • Expression Reminder: Expressions like have fun, have difficulty, be busy, and be worth always require an -ing gerund (had fun playing, difficulty understanding).

Common Mistakes with Gerunds and Participles

Because gerunds and present participles share the exact same -ing ending, students frequently confuse their grammatical roles. Master these five essential corrections to write clean, natural English.

Mistake 1: Assuming Every “-ing” Word Is a Gerund

An -ing word is only a gerund when it acts as a noun. If it describes an ongoing action or modifies a noun, it is a participle.

• “Swimming is fun.” ➔ Gerund (Subject noun).
• “Ali is swimming.” ➔ Present Participle (Continuous verb phrase).
Mistake 2: Using an Infinitive After a Preposition

Verbs that follow a preposition (without, by, in, about, before, after) must take the -ing (gerund) form:

❌ Incorrect: She left without to say goodbye.
✅ Correct: She left without saying goodbye.
Mistake 3: Confusing “-ed” and “-ing” Adjectives

Use -ing for the cause/stimulus and -ed for the person experiencing the emotion:

❌ Incorrect: I am exciting about the trip.
✅ Correct: I am excited about the trip.
• “The trip is exciting.” (The event causes the feeling).
• “I am excited.” (I experience the feeling).
Mistake 4: Creating a Dangling Participle

The subject immediately following an introductory participial phrase must be the person or thing performing that action:

❌ Dangling: Walking to school, the bus passed me. (Sounds like the bus is walking).
✅ Correct: Walking to school, I saw the bus. (Places the walker right after the comma).
Mistake 5: Confusing Gerund Phrases with Participial Phrases

Determine whether the entire phrase is functioning as a noun subject or as a descriptive modifier:

• “Swimming in the pool is fun.” ➔ Gerund Phrase (Acts as the subject noun).
• “Swimming in the pool, Ali waved to us.” ➔ Participial Phrase (Modifies Ali).

Quick Challenge

See the full explanation

Answer: “She left the office without saying goodbye to her colleagues.”

Core rules review:

  • Preposition Rule: Always use the -ing (gerund) form immediately following any preposition (without saying, by reading, before eating).
  • Adjective Distinctions: Use -ed for feelings (excited, bored) and -ing for the cause (exciting, boring).
  • Modifier Placement: Ensure introductory participial phrases point directly to the subject placed right after the comma.

Frequently Asked Questions About Gerunds and Participles

Get direct answers to the most common questions regarding gerunds (noun functions), present and past participles, phrase structures, and modifier rules in English grammar.

What is a gerund in simple words?
A gerund is an -ing form of a verb that acts as a noun.
• “Reading is fun.” ➔ Reading acts as the subject noun of the sentence.
What is a participle?
A participle is a verb form that can work as a descriptive adjective or as part of a continuous/perfect verb phrase:

• Present Participle (Verb/Adjective): “Ali is swimming.” / “The swimming boy waved.”
Do gerunds and present participles look the same? Is every “-ing” word a gerund?
Yes, they share the exact same spelling (-ing), but no, not every -ing word is a gerund. Their function in the sentence determines their identity:
  • “The boy is running.” ➔ Present Participle
  • “Running is good exercise.” ➔ Gerund
How can I quickly identify whether an “-ing” word is a gerund or a participle?
Use this quick diagnostic:
  • Gerund Test: Is the word acting as a noun (subject or object)? ➔ “Swimming is my hobby.”
