<Legion> looking at the grammar of French in a historical perspective, it gives the impression of a system desperatedly trying to catch up with way too enthusiastic sound changes...
<Legion> "okay so we just lost all final vowels except -a? ok, ok, I can fix this, there, we'll use -s to mark 1sg, yeah, that's nice, and maybe rework the subjunctive, merge the copulas, ok, we can work this out"
<Legion> *all final consonants are lost*
<Legion> "DAMMIT"
