Knot untied : 1
In the above sentence, to be to means "will", yet means "already". So, does
the sentence mean the best has already come or that it will come?
"Yet"
means "up to and including now", even when it's used with "to be
to [verb]". So the best has been coming for a while, and it continues to
come, but has not arrived yet.
The best is yet to come. (= The best has not come, but it will.)
