See yet in American Heritage Dictionary 4
Origin: Middle English
Origin: , from Old English gīet; see i- in Indo-European roots. 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.
