grammatical number - What's the correct plural form of "premise"?

Someone criticized me for using the word "premises" to denote a set of assumed "propositions", due to its connotation with houses and buildings.

Is that correct? If so, what should be the proper plural form of "premise"?

Answer

Merriam-Webster give an example using premises: premises of the argument>.

I do not think there is anything wrong with this use of premises. I don’t find homophony or having multiple meanings to be valid reasons to criticize use of a word.
