Non-finite verbs are, like finite verbs, considered an integral part of the English Grammar, what is more, they also find representation in the passive voice. Let’s have a look at what are they people call the non-finite. Non-finite verbs are identified with those that unlike the finite verbs can't make the predication complete. They are used as double parts of speech as the infinitive, the gerund and the participle.
THE INFINITIVE:
The
infinitive is the base form of the verb preceded by 'to' or without 'to.' e.g.
'It is almost impossible for a single man to carry a water-tank upstairs'. It
is an active voice in so far as the sentence emphasises on the ‘single man'
(agent or topic) and adds extra information (can’t carry a water- tank upstairs)
to the topic. Make note ‘it’ used here is a preparatory subject to refer
forward to the main subject or topic (a single man). The sentence turned into
the passive becomes ‘It is almost impossible (that) a water-tank to be carried
upstairs by a single man’. Infinitives have the sense of a noun combined with a
verb.
INFINITIVE FORMS IN TENSES:
Simple
infinitives in the active (to play)→simple infinitives in the passive (to
be played). Perfect infinitives in the active (to have played)→perfect infinitives in the passive (to have been played). Some more examples are ‘I don’t expect to be invited to
the ceremony’ ‘It is awful to be criticized in front of the followers’ and ‘The
man next door wanted the rubbish to be cleared away’. The third sentence when
reproduced in the passive voice becomes ‘The man next door wanted someone to
clear away the rubbish’. The same sentence could have been rewritten in the
perfect mode as ‘The man next door wanted the rubbish to have been cleared away
before he came back’ with a significant change in meaning as the time of the
perfect infinitive comes before that of the finite verb (wanted). The man
wished that the rubbish had already been cleared away. But we should at the
same time remember the time of the simple infinitive follows that of the finite
verb.
THE GERUND:
Gerunds
are often deemed as double parts of speech (a verb and a noun combined). They
are formed by adding ‘ing’ to the base (present) form of the verb preceding it.
Look at this chart here. Simple/present gerunds
in the active (playing)→simple/present gerunds in the
passive (being played). Perfect gerunds in the active (having played) → perfect gerunds
in the passive (having been played). A few examples of gerunds used in the passive are
‘I was afraid of being laughed at (passive)→I was afraid of people/people’s laughing at me (active). ‘I am annoyed
at having been made a fool of (passive)’. Here also the time of the perfect
gerund comes before that of the finite verb.
THE
PARTICIPLE:
Participles are
those words that refer to the present form of the verb combined with an ‘ing’
ending i.e. talking, playing, and walking.
Participles have a combined sense of both a verb and an adjective. ‘Having been
warned about the bandits, he left his valuables at home’, ‘Being hit with a
piece of stone, the man sat down bleeding’. These sentences when used in the
active voice read like ‘Someone having warned him about the bandits, he left
his valuables at home’ and ‘A piece of stone having hit him, he sat down
bleeding’.
HAVE:
Now compare these
three sentences given here: ‘The window was broken by a strong wind’ ‘A strong
wind broke the window’ and ‘Phil had one of his windows broken (by a strong
wind)’. There is absolutely no doubt as to how the first two sentences find
application in our everyday life, but the third one raises confusion as it
sounds a bit unfamiliar to some of us. ‘Have’ used this way can have two
different senses: causative and experience something.
HAVE+OBJECT+PRESENT
PARTICIPLES/ BARE INFINITIVES:
This construction
means that the subject causes somebody to do something. The sentence ‘The
teacher has/had us all singing/sing in the classroom’ gives the sense that the
teacher gives or gave us instructions to sing in the classroom, the present
participles usually denotes something in progress. The past participles
(participles ending in ed, t, n etc)
means ‘to cause something to be done’ and conveys a passive sense. Look at the
sentence’ ‘He had the letter signed’. It says he made somebody else to sign the
letter. ‘Have’ is mostly used here in the passive. ‘Get’ sometimes replaces
‘have’ to convey the causative sense but takes an infinitive with ‘to’; I am going to get my hairdresser to cut my
hair this evening when converted into a passive becomes I am going to get my hair cut this evening.
EXPERIENCE
‘Have+object+present/past
participle’ refers to an experience that somebody undergoes or something done
to him. ‘His sister had her purse stolen on the train’, ‘If you don’t use
pesticides you will have insects creeping up the stems’ and ‘My mother has had
her kitchen painted light brown’. All the three subjects of the three successive
sentences above underwent/will undergo or have undergone several experiences
mentioned in the sentences. For more about voices please read LEARN LANGUAGE: VOICES .
