An infinitive can also be referred to as a non-finite verb.
It usually begins with the word ‘to’ e.g to sleep, to walk, to run, to improve, to eat, to jump …so to identify whether the word is an infinitive put ‘to’ in front and see if the word makes sense.
In sentences the ‘to’ is removed e.g I can hear someone crying. (The ‘to’ has been removed from ‘to hear’)
