Gerund vs. Participle: Understanding -ing Word Functions
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."
This 11-question challenge will test your ability to identify gerunds and participles in various sentence contexts. You'll analyze -ing words and determine whether they function as nouns, adjectives, or parts of verb phrases. Try the quiz to check your knowledge!
Adjective
An adjective is a word that describes a noun or pronoun — giving more information about its quality, state, or identity. Adjectives sit either before the noun (a tall building) or after a linking verb (The soup is hot), and they answer questions like what kind?, which one?, or how many?
Getting adjectives right matters for two everyday reasons: their position is fixed (you can't say a redly dress), and when you stack several before a noun, English follows a strict order — opinion, then size, then age, then colour. Break that order and the sentence sounds off even when each word is correct.
Gerund
A gerund is the -ing form of a verb used as a noun — swimming, reading, being late. It can sit in any position a noun can: as the subject (Swimming is fun), as the object of a verb (I enjoy swimming), or as the complement of a preposition (She's good at swimming).
Gerunds matter because dozens of common English verbs and almost every preposition force you into the -ing form. Pick the wrong shape — I enjoy to swim, good at to swim — and the sentence sounds clearly off to a native speaker. Knowing which contexts demand a gerund (vs. an infinitive) is what makes verb patterns click.
Participle
A participle is a verb form that doubles as an adjective or adverb. English has two: the present participle ending in -ing (running, sitting) and the past participle (broken, gone, written). Both build tenses (is running, has gone), but they also stand alone modifying nouns (the broken window) or verbs (Exhausted, we fell asleep).
Participles look like simple parts of speech but pull double duty — most learner errors come from confusing the present participle with the gerund (also -ing but acting as a noun) or the past participle with the past tense.
Subject
The subject is the part of a sentence or clause that tells you who or what the sentence is about. It's typically a noun, pronoun, or noun phrase that comes before the verb and controls the verb's form: She works (singular) vs They work (plural).
The subject isn't always the doer of the action — in passive sentences, it receives the action (The window was broken). English also uses dummy subjects like it and there that hold the subject slot without carrying real meaning (It is raining; There are problems). Spotting the real subject is what makes subject-verb agreement automatic.
Verb
A verb is a word that expresses an action, a state, or an occurrence — the engine of every English sentence. Most verbs have five forms: base (go), -s form (goes), past tense (went), past participle (gone), and -ing form (going). The verb be is the major exception with eight forms; modal verbs like can and must have fewer.
Verbs carry tense (when), aspect (how it unfolds), mood (the speaker's attitude), and voice (active vs passive). Mastering them is foundational — virtually every other grammar topic depends on getting verbs right.
Progressive tense
The progressive aspect (also called continuous) marks an action as ongoing at the time of reference, formed with be + present participle (-ing): I am working, She was reading, They will be travelling. It signals temporary or in-progress events — the contrast with the simple aspect (I work = habit; I'm working = right now) is one of the most-used distinctions in English.
Some verbs (stative verbs like know, believe, own, belong) don't normally take the progressive — I'm knowing the answer sounds wrong. Recognising stative vs dynamic verbs is what stops you from over-applying the rule.
B1 | Intermediate
B1 is the intermediate level in the CEFR framework — the point where you stop relying on memorised phrases and start handling everyday English independently. At B1 you can describe experiences, explain opinions, and follow most clear standard speech on familiar topics like work, travel, and hobbies.
Grammatically, B1 means combining tenses with precision, building complex sentences, and starting to use passive voice, modal verbs for necessity and possibility, and verb patterns (gerund vs. infinitive). Knowing your level shapes what you study next: pushing too far ahead frustrates you; staying below your level wastes time.
Difficulty: Medium
The Medium difficulty tag marks questions and challenges in the middle of the difficulty range — typically suitable for A2 to B1 learners. Expect a single rule with realistic distractors, longer sentences, and contexts where you have to think before answering rather than reading off the obvious choice.
Filter by Medium when you're past the absolute basics and ready to consolidate. It's the level where most lasting progress happens — easy enough that you can finish without exhausting concentration, hard enough that getting it right means you've actually understood.
