1 Answer 1


We watched the workman to repair the machine.

Watch is an example of a verb of perception.

We can use either the infinitive without to or the -ing form after the object of verbs such as hear, see, notice, watch. The infinitive without to often emphasises the whole action or event which someone hears or sees. The -ing form usually emphasises an action or event which is in progress or not yet completed.

We could hence use either repairing or repair, as explained above and further in Cambridge Dictionary.
