Hi Mister Micawber,

[water to drink] can be [water to be drunk], why not can [a minute to spare] be [a minute to be spared]?

Thank you for your assistance.

Like much (or most) of English: the grammar is OK, but 'a minute to be spared' is not the restricted collocation in use. Almost 50% of English verb + noun collocations not free collocations but restricted collocations or idioms.

Hi,

I have a great idea from your talking to me, that [a minute to spare or to talk to or to do something for] are stressed

the matrix of saying on the doer not the receiver of the action of sparing.

To explain it,

I spare a minute for doing something for you. -------the matrix or subjectivity is the doer.

A minute is spared for doing something for you.

Hi,

I have an idea that noun + to-v is a set of a colloquial.

[water to drink]----unto water, to the men who drink;

= water is the thing according to the men who drink;

[water to be drunk]----unto water, to the thing that is drunk;

= water is the thing according to something else that is drunk;

Could any one to tell me correct or not?
