Grammar
e.g. You’ve been happy since I first met you.
B Using since, till and until
Since means from a certain time. The verb in the main clause is often used in the present perfect tense.
Till and until mean up to a certain time. Until can be placed at the beginning or in the middle of the sentence, but till is usually used in the middle of the sentence.
Grammar
e.g. Spud remained in another basketball league for about a year till/ until the NBA took notice of him.
Until his dream came true, Spud never gave up.
When we use the structure not…until, we cannot use till instead of until.
e.g. Don’t wake me up until you finish your work.
