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
If you've ever written a French nice old wooden table and felt something was wrong without knowing why, you've hit the adjective-order rule. English insists on a particular sequence — opinion, size, age, shape, colour, origin, material — and rearranging the words makes a sentence sound non-native even when every individual choice is correct.
An adjective describes a noun or pronoun: a tall building, the soup is hot. Most adjectives also take comparative and superlative forms (taller, tallest), which is how you compare things — another core piece you need from day one.
Gerund
If you've ever said I enjoy to read or good at to swim and wondered why it sounded wrong, you've met the gerund. English is fussy about which structures take -ing and which take to + verb, and getting this wrong is one of the most common giveaways that someone learned grammar from a list rather than from real usage.
A gerund is the -ing form of a verb acting as a noun — reading, swimming, being late. After many common verbs (enjoy, avoid, finish) and after every preposition, English demands the gerund, never the infinitive.
Participle
If you've ever written I should have went and been corrected to should have gone — you've hit the past participle's main rule. The participle isn't an exotic form; it's the workhorse that builds perfect tenses, passive voice, and dozens of common adjectives. Get the irregular ones automatic and your tenses fall into place.
A participle is a verb form acting as an adjective or adverb. The present participle is the -ing form (running, sitting); the past participle is -ed (regular: walked) or irregular (broken, gone, written). Participles build perfect tenses, progressive tenses, and the passive.
Subject
If you've ever written The list of items are wrong (should be is wrong) — you've hit the subject-agreement trap. The subject is list, not items, and the verb has to agree with it. Long sentences with prepositional phrases between the subject and verb are where this most often goes wrong, and getting it right is what stops careful readers from flagging your writing.
The subject is the part of a sentence or clause that says who or what the sentence is about. Typically a noun, pronoun, or noun phrase before the verb, controlling the verb's number and person.
Verb
If grammar feels overwhelming, the fix is almost always to focus on verbs first. They carry the action, the time, the mood, and the voice — a single verb form decides whether your sentence reads as past or present, fact or hypothetical, active or passive. Get verbs solid and the rest of grammar suddenly looks much smaller.
A verb expresses action, state, or occurrence — the engine of every English sentence. Most verbs have five forms (base, -s, past tense, past participle, -ing); be has eight; modal verbs have fewer. Verbs carry tense, aspect, mood, and voice.
Progressive tense
If you've ever paused over I work in London vs I'm working in London and not been sure which to pick — you've hit the simple/progressive distinction. The first means it's your usual job; the second means it's temporary, going on right now. Native speakers reach for this distinction constantly without thinking; learners have to make it deliberate.
The progressive aspect marks ongoing action at a time of reference, formed with be + -ing: I am working, She was reading, They will be travelling. Marks temporary or in-progress events. Stative verbs (know, believe, own) don't normally take it.
B1 | Intermediate
If you can hold a conversation about your weekend, explain why you're late, and follow a short news story without panicking — but still feel lost in fast or technical English — you're probably operating at B1. Knowing this matters: study material at the wrong level either bores you or burns you out, and B1 is the typical target for travel, casual work, and most everyday social English.
B1 is the intermediate level in the CEFR framework, where you handle everyday English independently and start combining ideas with complex sentences, passive voice, and modal verbs.
Difficulty: Medium
If easy questions feel too obvious but hard questions leave you guessing, you're probably ready for Medium — the level where most real learning happens. It pushes just enough to expose the rules you don't quite have yet, without burying you in edge cases. This is where steady fluency is built, one well-aimed challenge at a time.
The Medium difficulty tag marks middle-range challenges — typically A2 to B1. One rule per question, realistic distractors, and contexts that require active thought rather than instant recognition.
