Your B1 student wants to explain her morning routine. She reaches for the structure you’ve been working on and says: ‘I enjoy to read the news with breakfast.’ There’s that infinitive creeping in where a gerund should sit — a telltale sign that gerunds need more focused attention.
TL;DR
- A gerund is the -ing form of a verb that functions as a noun in sentences.
- B1 learners typically confuse gerunds with infinitives after certain verbs and struggle with preposition patterns.
What is a gerund and how does it work?
A gerund is an -ing verb form that acts as a noun in sentences. Unlike other -ing forms, gerunds occupy noun positions: subjects, objects, and complements.
Consider these examples: ‘Swimming improves fitness’ (subject), ‘She enjoys reading’ (direct object), or ‘His hobby is cooking’ (complement). In each case, the -ing word behaves exactly like a noun would.
The key insight for your students is that gerunds represent actions as things. When someone talks about ‘running’, they’re not describing the act of running in progress — they’re referring to the activity itself as a concept.
Gerund definition and examples
Gerunds transform verbs into nouns whilst keeping their -ing ending. They differ from present participles, which form continuous tenses (‘He is swimming’), and from present participles used as adjectives (‘running water’).
Here’s how to spot the difference:
| Function | Example | Role in sentence |
|---|---|---|
| Gerund (noun) | ‘Smoking causes cancer’ | Subject |
| Present participle (verb) | ‘He is smoking’ | Part of continuous tense |
| Present participle (adjective) | ‘smoking chimney’ | Describes a noun |
The noun substitution test works brilliantly here. Replace the -ing word with ‘something’ or ‘it’. If the sentence still makes sense, you’ve found a gerund: ‘Something causes cancer’ works perfectly.
How do you identify gerunds in sentences?
The most reliable method for identifying gerunds is the noun substitution test. Replace any -ing word with ‘something’ and check if the sentence remains grammatically sound.
Take ‘Walking helps clear your mind.’ Substitute ‘something’ for ‘walking’: ‘Something helps clear your mind.’ The sentence works, confirming ‘walking’ functions as a noun — a gerund.
The noun substitution test
This test works because gerunds occupy the same positions as regular nouns. Students can practise by taking any sentence containing an -ing word and applying the substitution.
Try it with ‘I’m interested in learning Spanish.’ Replace ‘learning’ with ‘something’: ‘I’m interested in something Spanish.’ The grammar breaks down, but that’s because we need ‘I’m interested in something’ — confirming ‘learning’ is indeed a gerund functioning as the object of the preposition ‘in’.
Common gerund positions
Gerunds appear in three main sentence positions, each serving a different grammatical function.
As subjects, gerunds often open sentences: ‘Walking helps fitness’, ‘Cooking requires patience’. Students find this pattern easier to grasp because the gerund sits where they expect to find a noun.
As objects, gerunds follow specific verbs: ‘He enjoys cooking’, ‘They avoid talking about work’. This requires explicit teaching because learners can’t predict which verbs take gerunds versus infinitives.
After prepositions, gerunds are mandatory: ‘interested in learning’, ‘good at swimming’, ‘tired of waiting’. The preposition forces the gerund form — never an infinitive. This B1 gerund lesson on productivity habits demonstrates these patterns through authentic contexts.
| Sentence | Gerund | Function |
|---|---|---|
| ’Teaching requires preparation’ | Teaching | Subject |
| ’She loves dancing’ | dancing | Direct object |
| ’He’s good at listening’ | listening | Object of preposition |
What are the most common gerund errors students make?
Gerund errors at B1 level cluster around two main areas: gerund versus infinitive confusion after verbs, and missing or incorrect prepositions before gerunds.
The most frequent mistake involves using infinitives where gerunds are required. Students produce ‘I enjoy to swim’ instead of ‘I enjoy swimming’ because they overgeneralise the verb + to + infinitive pattern.
Gerund vs infinitive after verbs
Certain verbs demand gerunds as direct objects, whilst others require infinitives. There’s no logical pattern — it’s purely lexical, which makes it challenging for learners.
Common gerund-taking verbs include enjoy, finish, avoid, suggest, mind, and practise. Students often hear ‘I finished to write my essay’ in class, when the correct form is ‘I finished writing my essay’.
Group these verbs semantically rather than alphabetically. Teach likes and dislikes together (enjoy, love, hate, can’t stand + gerund), then move to completion verbs (finish, stop, quit + gerund). This B1 gerund lesson on productivity habits organises patterns this way, making them more memorable.
Missing or incorrect prepositions
Students frequently drop required prepositions before gerunds or add unnecessary ones after verbs that take gerunds directly.
Typical errors include ‘interested learning’ (missing ‘in’) or ‘enjoy about playing’ (adding unwanted ‘about’). The first happens because students focus on the verb-gerund connection and forget the preposition. The second occurs when they overgeneralise verb + preposition + gerund patterns from other structures.
Phrasal verbs create particular difficulty. ‘Look forward to seeing you’ requires ‘to’ plus a gerund, not an infinitive — but students hear ‘to’ and instinctively reach for ‘look forward to see you’.
| Error type | Wrong example | Correct form |
|---|---|---|
| Missing preposition | ’interested learning' | 'interested in learning’ |
| Wrong verb pattern | ’enjoy to swim' | 'enjoy swimming’ |
| Preposition confusion | ’look forward to see' | 'look forward to seeing’ |
How can you teach gerunds effectively in the classroom?
The most effective gerund teaching sequence starts with authentic contexts before explicit rules. Students notice patterns in real usage first, then work out the grammar consciously.
Begin with a text or video where gerunds appear naturally — lifestyle habits work particularly well because they generate genuine gerunds (‘I enjoy cooking’, ‘I avoid exercising’, ‘I’m good at multitasking’).
Inductive noticing activities
Start your lesson by showing students sentences from authentic sources without mentioning gerunds. Give them a text about someone’s daily routine and ask them to underline all the -ing words.
Next, put students in pairs to categorise their findings. Which -ing words are part of ‘be + -ing’ (continuous tenses)? Which ones could be replaced with ‘something’ and still make sense? This second group contains your gerunds.
Only after this discovery phase should you provide the explicit rule. Inductive teaching approaches for gerunds support meaning-focused learning by letting students spot patterns themselves. This B1 gerund lesson on productivity habits uses exactly this sequence with authentic video content.
Semantic grouping approach
Gerund and infinitive verb patterns stick better when taught in semantic groups rather than random lists. Students connect meaning with form more easily.
Group preference verbs (enjoy, love, hate, don’t mind + gerund) together in one lesson. The semantic connection helps: these verbs all express attitudes towards activities-as-things, which is exactly what gerunds represent.
Teach completion and cessation verbs (finish, stop, quit, give up + gerund) as another group. Again, the meaning supports the form — you complete or cease doing activities, not plans to do activities. Semantic grouping strategies for verb patterns create stronger form-meaning connections than random memorisation.
Production and error correction
End your gerund lesson with personalised speaking tasks that integrate grammar with fluency. Give students conversation prompts that naturally elicit gerund patterns: ‘What do you enjoy doing at weekends?’, ‘What are you good at?’, ‘What can’t you stand doing?’
Design peer correction activities where students must notice and correct each other’s gerund errors during conversation. When someone says ‘I enjoy to cook’, their partner stops them and provides the correction before they continue.
| Stage | Activity | Time | Focus |
|---|---|---|---|
| Warm-up | Lifestyle habits questionnaire | 10 min | Context setting |
| Noticing | Categorise -ing words in text | 15 min | Pattern discovery |
| Clarification | Gerund rules and examples | 10 min | Explicit teaching |
| Practice | Semantic verb groups drill | 15 min | Form accuracy |
| Production | Personalised conversation | 10 min | Fluency integration |
This structure moves from meaning to form to use — exactly what adult learners need for lasting acquisition. ESL Brains’ library contains 1,000+ video-based lesson plans covering levels A1 to C2, with authentic materials that make gerund teaching feel relevant and engaging.
Frequently Asked Questions
What is the difference between a gerund and a participle?
A gerund functions as a noun (‘Swimming is fun’), while a present participle acts as a verb (‘He is swimming’) or adjective (‘running water’). The noun substitution test helps distinguish them.
How do you identify a gerund in a sentence?
Replace the -ing word with ‘something’ or ‘it’. If the sentence still makes grammatical sense, you’ve found a gerund. For example: ‘Reading helps relaxation’ becomes ‘Something helps relaxation’.
What are the most common mistakes students make with gerunds?
B1 learners typically use infinitives where gerunds are required (‘I enjoy to read’ instead of ‘I enjoy reading’) and struggle with preposition patterns before gerunds.
Can all verbs be used as gerunds?
Yes, all verbs can form gerunds by adding -ing. However, not all verbs can be followed by gerunds - this depends on specific verb patterns that must be learnt.
