"There’s something out there that has a lot of people scared, but no one’s telling the full story. Yet.

For months and weeks, bits and pieces of the story of Donald Trump, Vladimir Putin, Russian intelligence and its influence on the 2016 elections have been dribbling out, thanks to leaks and solid reporting by a free and independent press.

Eventually we may get to the whole truth, but already it seems clear that deep down, all these secrets coming to light, one by one, are part of a greater wrong." - Michael Winship

as yet

1. Up to the present time; up to now.

[Middle English, from Old English gīet.]

USAGE NOTE In formal writing, yet in the sense “up to now” is normally used with an accompanying verb in the present perfect rather than in the simple past. Thus, one would say He hasn't started yet, not He didn't start yet. The use of yet with the simple past is common in speech and may be appropriate for informal writing.

Definition of as yet in English:

[USUALLY WITH NEGATIVE] Until now or a particular time in the past:the damage is as yet undetermined-----

Apparently from as yet, by confusion with as of.

Adverb[edit]

as of yet (not comparable)

1. (perhaps nonstandard) Alternative form of as yet
