#please appreciate my restraint in not talking about grammaticalization in response to this very simple question

[official-linguistics-post]

I feel like we see new verbs adjectives and nouns pop up all the time. Are there any examples of new conjunctions or prepositions (or similar) being made?

function words like conjunctions and prepositions fall into what we call "closed lexical categories" - they're very resistant to innovation, being so integral to syntactic structure. verbs, adjectives, and nouns are all open categories and readily accept new forms.

I would like to talk about grammaticalization, please. (Even though my computer's dictionary claims that it is not a word.)
