Question

(d) Who was very tired, use who​

Answer 1

Answer:

the word “is” is a linking verb. It is similar to an equals sign in an equation (A + B = C). The equation for this sentence would be:

He (subject) = very (adverb describing “tired”) tired (adjective describing “He”)

The word “is” is used for third person singular verbs (he is, she is, it is) and comes from the verb “to be.”

Note that “is” and all forms of “to be” can be used as auxiliary words when combined with the present or past participle of another verb. In that case, the mathematical equation illustration does not work (e.g., “He is working” or “Leather is used for making purses”).
