Honestly I think my favorite part of conlanging is making the contractions, clitics, reduced forms, tag questions, fillers, backchannels, the likes
The types of words that might get one's speech stereotyped as "lazy" or "disfluent" or "uneducated" or whatever else if used excessively or in too formal a setting, but which in truth are vital for fluency and listening comprehension....
