I just looked up the pronunciations, wondering whether I was pronouncing them correctly, and noticed in MW that there are two somewhat different pronunciations of prosthesis. The one with the accent on the first syllable was new to me.

Anyway, it would be fun to read here some tongue-twisters working prosthesis, prosthetics, and prosthetist...

Our host's prosthetist's list of prosthetics theses suggests best prostheses hypotheses.
