Tamilnadu Samacheer Kalvi 12th English Grammar Modals
General Characteristics Of Modals
1. Modals are never used alone. A Principal verb is either present or implied;
as—
I can sing. He will help you.
2. Modals do not change according to the number or person of the subject;
as—
I can. We can. You can. He can. They can. etc.
I may. We may. You may. He may. They may. etc.
3. Modals have no Infinitive, Present Participle or Past Participle forms.
4. Modals cannot be used in all the tenses. When a modal does not fall in this pattern, it works as a Principal Verb;
as—
God willed so.
Henry needs a pen.
Malathi dared to go into the dark forest.
(Here will, need and dare are used as main verbs)
Relationship of Modals with Tenses
(i) May, can, shall and will are in present forms while might, could, should and would are their past forms.
The two forms express different meanings, but usually, no difference of time, e.g. the difference between may and might is often that of a degree of probability,
as—
Sheela may come today. {possibility/likely to happen)
Sandra might come today. (remote possibility/less likely)
(ii) However, if the verb in the main clause is in the past tense, the forms might, could, should and would serve as regular past tenses;
as—
1. He said, “I can help you.”
He said that he could help her.
2. You said, “She will come back soon.”
You said that she would come back soon.
3. Sheetal said, “May I use this pen, madam?”
Sheetal asked her teacher if she might use that pen.
(iii) When we want to express the past time in verb phrases involving modals, we use the Present Perfect Tense of the Principal Verb; as-
Senthil must have reached home by now.
You ought to have told me all the facts.
