Gerund vs. Participle: Function of -ing Words
Words ending in -ing can serve very different grammatical functions in English, and distinguishing between gerunds and participles is essential for understanding sentence structure. A gerund functions as a noun and can act as a subject, object, or complement. For example, in "Swimming is great exercise," the word "swimming" is a gerund serving as the subject. In contrast, a participle functions as an adjective, modifying a noun or pronoun, as in "The swimming instructor gave us tips," where "swimming" describes the instructor.
The key to identifying whether an -ing word is a gerund or participle lies in analyzing its role within the sentence. Ask yourself: Is the -ing word naming an activity or thing (gerund), or is it describing a noun (participle)? Consider these examples: "I enjoy reading" (gerund as direct object) versus "The reading lamp needs a new bulb" (participle modifying "lamp"). Additionally, present participles can form part of continuous verb tenses, such as "She is working," where "working" combines with the auxiliary verb "is."

Drag the correct grammatical labels to identify each -ing word's function.
You're chatting with a friend about weekend activities. Look at these sentences and label each -ing word correctly!
"Cooking is my favorite hobby." → Gerund (noun/subject)
"The boiling water splashed everywhere!" → Participle (adjective)
"I was watching a cooking show." → Participle (verb part)
Cooking → Gerund (noun/subject)
In "Cooking is my favorite hobby," you can replace "cooking" with a noun like "It" — so it's a gerund functioning as the subject.
boiling → Participle (adjective)
In "The boiling water," the word "boiling" describes the noun "water" — so it's a present participle functioning as an adjective.
watching → Participle (verb part)
In "I was watching," the -ing word combines with "was" to form the past continuous tense — so it's a present participle as part of the verb phrase.
The correct answers are That was the most boring film I've ever seen and The surprising ending made everyone gasp.
"Boring" is a present participle functioning as an adjective describing "film." "Surprising" is a present participle functioning as an adjective describing "ending." In the other sentences, "Watching" and "reading" are gerunds acting as nouns (subject and object, respectively).
The correct answer is gerund (noun/subject).
"Swimming" functions as a gerund — it's the subject of the sentence, acting as a noun. You can replace it with any noun: "Exercise keeps me healthy."
Drag each -ing word to its correct function category.
You're reviewing a movie with a friend. Sort these -ing words by how they're used!
"I enjoy watching thrillers." → Gerund
"That was an exciting plot twist!" → Participle (adjective)
"Sitting through a three-hour film is exhausting." → Gerund
"The sleeping audience missed the ending." → Participle (adjective)
watching → Gerund
In "I enjoy watching," the word "watching" is the object of the verb "enjoy." You could replace it with a noun: "I enjoy movies." That's the gerund test!
exciting → Participle (adjective)
In "an exciting plot twist," the word "exciting" describes the noun "plot twist" — it's a present participle working as an adjective.
Sitting → Gerund
In "Sitting through a three-hour film is exhausting," the gerund phrase is the subject of the sentence. Replace it with "It" and the sentence still works!
sleeping → Participle (adjective)
In "the sleeping audience," the word "sleeping" describes the noun "audience" — it's a present participle functioning as an adjective.
The correct answers are Learning new languages are challenging but rewarding and Eating vegetables every day are good for your health.
A gerund phrase as subject is treated as a singular unit, so it takes a singular verb. "Learning new languages is challenging" and "Eating vegetables every day is good" are the correct forms. The verb must agree with the gerund phrase, not with the noun inside it.
The correct answers are Cooking relaxes me after work and She enjoys painting on weekends.
"Cooking" in "Cooking relaxes me" is a gerund functioning as the subject (noun). "Painting" in "She enjoys painting" is a gerund functioning as the object (noun) of "enjoys." In the other sentences, "cooking," "studying" are present participles forming part of continuous verb phrases ("am cooking," "were studying").
The correct answer is participle (adjective).
"Fascinating" is a present participle functioning as an adjective — it describes the noun "documentary." It's NOT a gerund because it doesn't act as a noun itself.
The correct answer is is.
"Learning new languages" is a gerund phrase acting as the subject. Even though "languages" is plural, the entire phrase counts as a single unit, so it needs the singular verb "is." ✗ "are" → ✓ "is"
The correct answers are Swimming keeps me healthy and I love hiking in the mountains.
"Swimming" is a gerund acting as the subject (noun) of the sentence. "Hiking" is a gerund acting as the object (noun) of "love." In contrast, "swimming" in "swimming pool" is a participle describing the noun "pool," and "dancing" is part of the continuous verb phrase "is dancing."
Your classmate is describing their study routine. Look at the two sentences below and identify the different functions of the -ing words.
Sentence A: "I enjoy studying in the library."
Sentence B: "I am studying in the library right now."
Which statement correctly identifies both -ing words?
The correct answer is In A, "studying" is a gerund (object); in B, "studying" is a present participle (part of a verb phrase).
In Sentence A, "studying" follows the verb "enjoy" and acts as its object (noun) — that's a gerund. In Sentence B, "am studying" forms the present continuous tense, so "studying" is a present participle.
Adjective
Adjective vs adverb: both describe things, but adjectives attach to nouns while adverbs attach to verbs. A quick answer (adjective → noun) vs answered quickly (adverb → verb).
An adjective modifies a noun or pronoun — telling you what kind, which one, or how many: a red car, something useful, three heavy boxes.
Diagnostic test: if the word describes a thing or person, use the adjective form. If it describes an action, you need the adverb (-ly) form instead.
Gerund
Gerund vs infinitive: the biggest source of errors for non-native speakers. Some verbs take only gerund (enjoy reading ✅), some only infinitive (want to read ✅), some take both with different meanings (stop reading ≠ stop to read). There's no logical rule — these must be learned by verb.
A gerund is the -ing verb form used as a noun. After prepositions = always gerund. After certain verbs (enjoy, avoid, finish) = always gerund. After to (preposition, not infinitive marker) = gerund (I look forward to seeing you).
Diagnostic: can you replace the -ing word with "it" or "something"? I enjoy it → yes, it's acting as a noun = gerund.
Participle
Present participle vs gerund: both are -ing forms, but a participle acts as an adjective/adverb (the running water, She sat reading), while a gerund acts as a noun (Running is fun). Same form, different grammatical job.
A participle = verb form used as modifier or in compound tenses. Present (-ing): progressive + adjective. Past (-ed/irregular): perfect + passive + adjective.
Diagnostic: is the -ing word describing a noun or modifying a verb? → participle. Is it being a noun (subject, object)? → gerund.
Subject
Subject vs object: the subject does or is; the object receives. She (subject) hit him (object). In English, position decides: subject comes before the verb, object after. Unlike inflected languages, English rarely marks subjects with case (exception: pronouns — I vs me).
The subject = who/what the sentence is about. Controls verb agreement. Usually a noun/pronoun before the verb.
Diagnostic: ask "who or what [verb]s?" The answer is the subject. The list of items is wrong — what is wrong? The list. That's your subject.
Verb
Verb vs noun vs adjective: nouns name things. Adjectives describe. Verbs express what happens or what IS. The test: can it take tense (walked, will walk)? Can it take -ing? Can it follow to as an infinitive (to walk)? Yes to any → verb. English often converts freely between classes (run = noun or verb), so context decides.
A verb = action/state/occurrence word. 5 forms (base, -s, past, past participle, -ing). Carries tense, aspect, mood, voice. The one required element in every sentence.
Diagnostic: does it change for tense (walk → walked)? Can you put to before it (to walk)? Does it take -ing (walking)? → verb.
Progressive tense
Progressive vs simple: I work in London (permanent job) vs I am working in London (temporary assignment). Simple = fact/habit/permanent. Progressive = ongoing/temporary/in-progress. Same verb, different aspect, different meaning. The choice isn't about grammar preference — it changes what you're communicating.
The progressive = be + -ing. Marks ongoing/temporary actions. Stative verbs resist it.
Diagnostic: is the action happening RIGHT NOW and likely to stop? → progressive. Is it a general truth, habit, or scheduled event? → simple. Is the verb stative (know, own, believe)? → simple (even if happening now).
B1 | Intermediate
B1 vs B2: B1 handles standard everyday communication and simple opinions. B2 handles abstract topics, sustained arguments, and nuanced register. If you can chat about your life but struggle to debate an issue or write a formal essay, you're B1.
B1 is the intermediate CEFR level: independent handling of familiar topics, second conditional, basic passive, reported speech, and linking words for cause and contrast.
Diagnostic: can you read a newspaper article on a familiar topic and summarise the argument? Comfortably → B2. Struggle with abstractions → still B1.
Medium
Medium vs Easy: Easy has one obviously correct answer and clearly wrong distractors. Medium has one correct answer but plausible distractors — you need to actually know the rule, not just guess from sound.
The Medium tag filters for A2–B1 challenges with realistic difficulty: one rule per question, plausible alternatives, everyday contexts.
Diagnostic: if you're scoring 90%+ on Easy, move here. If you're below 60% on Medium, go back to Easy for that topic. Target 70–80% accuracy for maximum learning.
