*"Yet" can be rarely used in an affirmative sentence,means like"as late as, until,now or then" or "again,in addition"="more and yet more". Examples: -There is yet time!=This is as late as time! -It's my best work yet.=It's my best work now. -"Do i need to make more cupcakes,sir?"-"More and yet more,my dear chef!" *In a negative or interrogative sentence: Examples:-It's not time to give up yet! -Have you finished your schedule yet? *In a comparison: it means like"even" Example: How about our next task?Is it difficult as the first one?"-"It's a yet more difficult task!=It's even more difficult than the first task!"

yet can have two meanings. yet = by now, till now like in the previous example, I have not yet seen the film = I have not seen the film till now. Yet = still I asked him not to go out in bad weather yet he went = I asked him not to go out in bad weather still he went hope this helps. :)

'Yet' can be used in an affirmative sentence, but it is very rare and sounds outmoded. It is almost always used in a negative sentence. "I have not yet seen the film." "I am not finished yet." One sentence that sounds affirmative, but is actually negative is: "I have yet to see a totally honest politician." = "I have not yet seen an honest politician."
