Description

I discovered that many nouns ending in -th did not have their plurals marked properly.

Other than that, mostly POS tweaks due to posslq
-common - not noun
-couchette - generate possessive
-coughs - plural & 3rd pers sg pres
-could - not noun
-here - not adj
-king - don't generate kingly
-queen - don't generate queenly
-setting - split into sg and pl entries
-went - not noun
-wept - past tense & participle
