-ique, -ic, -y, -ie... 

Spellings which are now considered archaic -ique (poetique, musique, logique...) a replaced almost anywhere with -ic (poetic, music, logic...) but retain in some falls (unique, critique, relique, antique, technique...), should also be included. Same fall is with spellings -y (allegory, memory, melancholy...) to -ie or -ia (allegorie, memorie, melacholie...), and silent e (poete, mythe, sexe...) instead of more common spellings (poet, myth, sex...).
