Old timey vocabulary: Bleak House edition

From the first half of Bleak House:

ait – a small island, esp. in a river. In green aits and fields…
nosegay – a bouquet of flowers. I knew this one.
patten – a sort of clog worn to give height or keep one out of the mud. I would have guessed some sort of special mitten.
pattening – can’t find anything for this one. Possibly a misprint of “patterning?” It has to do with clothes.
purblind – partially or totally blind. I’m thinking it’s related to “par-boiled.”
weazen – like wizened, but with 100% more ea. Suffix optional.
tapis – a carpet or tapestry.
prolixity – of unnecessary or tedious length. Wordy.
prosing – to speak or write in prose, usually in a dull way. I thought so, just making sure.
paviour – a paving material or person who paves. Might as well just say “paver.”
emolument – profit or fees resulting from labor. Pay, essentially.
nankeen – some sort of yellowish clothing made from Chinese cotton. Makes sense.
desultory – haphazard, inconsistent, tangential (unrelated to sultry)

O Lord!
