forms part

I suggest saying: "The household income is a required entry on the application for membership.

Hi,

Client was wondering whether there is a separate form to be completed when applying for a membership, specifically declaring the household income.

Should I say?

The household income forms part of the membership form or

The household income is formed part of the membership form

Hello, Tony—Your second example is ungrammatical, but the first one is OK. If I were you, however, I would omit "The" at the beginning and simply say:

• Household income forms part of the membership form.

The sentence that f6pafd has suggested also works nicely.

Thanks David! so in what circumstances we can use "is formed part"?

Hi, Tony C.  Please read David's post again. He told you that your second example is ungrammatical; therefore, under no circumstances should you use it.

Hello again, Tony—As f6pafd says, it should never be used, because it is ungrammatical. The reason it is ungrammatical is that "is formed" is either a passive construction or a linking-verb-plus-adjective construction.

If it is a passive construction, it cannot be followed by the direct object, since the direct object will have been promoted to subject. If it is a linking-verb-plus-adjective construction, then a preposition is needed after the adjective.
