Verbs followed by infinitives: choose the next verb

Whenever two verbs appear side by side in a clause, the first verb dictates the structure of what follows. Many common verbs that point toward a future outcome or purpose demand to plus a base verb. If you identify want, decide, or plan as the governing verb, you can immediately prepare the infinitive pattern for the incoming action without guessing.

A verb complement pattern depends entirely on the first verb, not the noun that comes before it.

Learners frequently feel tempted to add verb endings to the second verb, especially when writing about the past or talking about a third-person singular subject. In the infinitive structure, the word to must be followed by an uninflected base verb. No matter what tense or subject appears earlier in the sentence, never add an s, ed, or ing suffix to that second action.

Infinitive particles freeze the following verb into its dictionary shape.

You can practise this again in Said or Told: Choose the Right Verb and Action Verbs: Choose What Happens.

Verbs that describe making up your mind or organizing future actions regularly take to plus a base verb. Common verbs in this category include plan, decide, choose, and prepare. When you discuss career moves, travel schedules, or weekly tasks, using this pattern signals that a deliberate choice has been reached before the action occurs.

Learn plan to, decide to, choose to, and prepare to as patterns. Similar meanings do not always mean that verbs take the same form afterward.

In professional and personal negotiations, you often discuss obligations, commitments, and mutual terms. Verbs such as need, promise, agree, and refuse link to subsequent actions using to plus a base verb. This structure clarifies who is bound to perform an action and what specific commitment has been accepted or rejected.

Verbs of commitment and necessity lock their complements into to plus a base verb.

Tense markers and subject-verb agreement belong entirely on the governing verb, never on the infinitive. If a story moves from the present to the past, change want to wanted or decide to decided. The subsequent verb remains unchanged. Observing this division prevents awkward double-marking in sentences with compound time references.

Only the primary verb carries tense inflections in a verb plus infinitive structure.

Not every common English verb permits an infinitive. Verbs like enjoy, avoid, practice, and suggest require a gerund ending in ing instead. Mixing these two patterns is one of the most common errors at intermediate levels. Rather than assuming to works everywhere, you must check whether the lead verb belongs to the infinitive group or the gerund group.

Verbs like enjoy and avoid never take an infinitive complement in standard English.

A small group of verbs can take either an infinitive or an ing form, but the meaning changes distinctly. The verb try is a clear example. When you say try to do something, you mean making an effort to overcome a difficulty. When you say try doing something, you mean experimenting with a method to see if it solves a problem.

Try to emphasizes effort and difficulty, while try plus ing emphasizes testing an experiment.

To often has a weak pronunciation in connected speech. Before a consonant, /tə/ is common; before a vowel, /tu/ is also common. An emphasized to can have a full vowel. Listen to the recording rather than assigning one weak form to every sentence.

A weak form can link to the following verb, but to does not have one fixed reduced vowel in every context.
