Non-finite Verbs

Expressing purpose

A2 Elementary

Expressing purpose explains why someone does an action using 'to' followed by a verb or 'for' followed by a noun.

Gerunds and Infinitives (complex forms)

B2 Upper Intermediate

Complex gerunds and infinitives allow speakers to express actions that happened before the main verb or to use the passive voice within these structures.

Gerunds and Infinitives as subjects/objects

B1 Intermediate

Gerunds and infinitives can function as nouns within a sentence, acting as the subject or the object of a verb. While gerunds are more common as subjects in daily speech, infinitives often appear in formal or poetic contexts.

Infinitive of purpose

B1 Intermediate

The infinitive of purpose uses the 'to + verb' form to explain why someone performs an action. It is a concise way to express the reason or goal behind a specific behavior.

Like/hate/love + -ing

A1 Beginner

Use the -ing form of a verb after like, love, hate, and enjoy to talk about general preferences and hobbies.

Preposition + -ing

B1 Intermediate

In English, when a verb follows a preposition, it must take the -ing form (the gerund). This rule applies to all prepositions, including those following adjectives, nouns, or other verbs.

Reduced relative clauses

B2 Upper Intermediate

Reduced relative clauses shorten a sentence by removing the relative pronoun and the verb 'to be'. They use present or past participles to modify nouns more concisely.

Too...to / Enough...to

B1 Intermediate

Use 'too' and 'enough' with adjectives and adverbs to describe the degree of a quality in relation to a specific action or purpose.

Verb + -ing

A2 Elementary

Certain English verbs are followed by a second verb in the -ing form (the gerund) rather than an infinitive. This structure is common when discussing likes, dislikes, and the beginning or end of activities.

Verb + object + infinitive/gerund (advanced)

B2 Upper Intermediate

This guide covers complex verb patterns where an object is followed by either a bare infinitive, a to-infinitive, or a gerund, focusing on verbs of perception and causation.

Verb + object + to-infinitive

B1 Intermediate

This structure describes how we use a verb to influence or direct another person's actions. It is commonly used for requests, orders, advice, and desires.

Verb + to-infinitive

A2 Elementary

This guide explains how to use a second verb in the to-infinitive form after specific main verbs like want, need, and hope.

Verb + to-infinitive (basic)

A1 Beginner

This guide explains how to use a main verb followed by a 'to-infinitive' to express desires, plans, and needs.

Verb patterns (change in meaning)

B1 Intermediate

Certain verbs change their meaning depending on whether they are followed by an -ing form or a to-infinitive. Understanding these shifts is essential for describing memories, efforts, and future obligations accurately.
