Precipitate / hasty

[Mnemon]

Hi.

a. Don’t be hasty.

b. Don’t be precipitate.

Do they both sound idiomatic to you?

Thank you.

The second is not common.

The second is not common.

I agree. Precipitate is preferred over hasty by people who won't use a plain word if a fancy one is available.

 

[Tarheel]

I've never even heard of that word before.

Probably, it's of high register and not used in everyday conversation.

 

[Tarheel]

It's definitely not used in everyday conversation. (I'm going to have to look up "higher register".)

There are three meanings for the word precipitate.

I learned the first meaning in chemistry in school -an insoluble, solid substance formed by mixing two solutions in a test tube. The second is "to cause an unpleasant event to be formed unexpectedly", which is consistent with the phenomenon in chemistry. The third meaning which is the adjective used here is quite obscure.

I agree that it is not common, but I would not call it 'obscure'.
