De'vID:
How would you express "before now"? "I haven't done
this (e.g., written a manuscript) before now."
{ret not ghItlh vIqon}? Can {ret} be used by itself as
a time stamp, and can it precede an adverbial {not}?
SuStel:
wej vIta'pu'.
wej ghItlh vIqonpu'
It doesn't quite have the same sense or emphasis, though. {wej} "not
yet" connotes a sense of anticipation that "not before now" does not.
"I haven't yet done it" suggests that the speaker intends to do it,
but hasn't yet. But "I haven't done it before now" implies nothing
either way - perhaps the speaker intends to do it, but perhaps not.
