never ever
not while pussy's a cat
when two Sundays come together
nevah
when two Sundays meet
never've
unreddened
nooit
when Hell freezes over
future-day
Neveruary
at latter Lammas
if pigs had wings
when pigs fly
at no time
at the earliest
uneverted
pre-dead
NN
nary
in a pig's eye
unreached
ungained
no more
only if
no longer
only
at the latest
only when
unforeseen
nonpending
futurity
seldomly
time to come
future
hereafter
unborn
nonemerging
under no circumstances
nevermore
nothing like
previable
unslaked
unmade
nontillable
unchanced
untillable
in no way
nonimmediate
second Tuesday of the week
