Hi Unizeta, re 5d.,
Chambers has a def. of 'time' for SITH. Also from Wiktionary ...
From Middle English sith (“journey, movement, lifetime, period, occasion”), from Old English sīþ (“journey, movement, trip, point in time, occasion”), from Proto-West Germanic *sinþ, from Proto-Germanic *sinþaz, from Proto-Indo-European *sent- (“to go, head”).
For 33a. I have DISEUSE, from French, entertainer.
