Yes, perhaps I have too much time on my hands

This is just a thought, but I thought I might, and would encourage the rest of you to do so too, jot down a couple of words, I would prefer to not see disappear from the English language. I have no ethical reason for wanting this, it is more a quality of life sort of thing. So here are some, I'll be adding more now and then, and I hope you will too.

swizzle (as in swizzle stick)
welkin
swivel
guzzle
megrims
daft
palaver
jejune
muck
dreary
pustule
perambulator
catamite
filch
improbity
defenestration
truss
umbo
