Three Golden Rules ( Primary Verbs)


Primary verbs can be used as auxiliary verb and main verb:

For example:

I am Joseph.( ‘am’ used as main verb)

I am going to the market. ( ‘am’ used as auxiliary verb)

I have a pen.( ‘have’ used as main verb)

I have bought a pen.( ‘have’ used as an auxiliary verb)

Does Joseph go to the market everyday? ( “do” is used as main verb)

Joseph did that act.( “do” is used as an auxiliary verb)

Three golden rules:

1. When the forms of to be (am, are, is, was, were) used as auxiliary verbs the main verb must be in “ing” form .

2. when the forms of to have (have, has, had) used as auxiliary verbs the main verb must be in past participle form,

When the forms of to do (do, does, did) used as auxiliary verbs, the following main verb must be in infinitive form.

Note: These rules are applicable only in active voice.
