they had to carefully remove the eggs from the nest identify the infinitive

Sayan 26th Aug, 2022


They had to carefully remove the eggs from the nest.

Infinitive verb : to

Note : The second most fundamental form of a verb is an infinitive. Simply use the word "to" before the verb when employing an infinitive to utilise it correctly. Both finite and nonfinite verbs are possible. Verbs with a subject and tense are referred to as finite verbs. They are conjugated with "-ed" or "-ing" and can refer to one or more things. By adding "-s" to the end, they can also be conjugated in the third person singular.
