till and until

Question

what is the different between  till and until ?

Explain with examples please .

Answer 1

According to Michael Swan:

Until and till can be used both as prepositions and conjunctions. They mean exactly the same. 

Till is informal British (in American English, 'til is the preferred informal spelling).

I won't expect you until/till midnight.

I'll wait until/till I hear from you.

The new timetable will remain in operation until June 30.

This has always been a question for we as to which one to pick while making up the sentences in mind. Thank you hossein_p199 for asking it and thank you  Sarah  for sharing your knowledge with us.

Answer 2

(Till itself comes from a very old Old English word til, “to.” Until was formed from till by the addition of the prefix un-, which meant “up to.” So etymologically at least, until is a self-contained redundancy, meaning “up to up to.” You can use till and until interchangeably in both writing and speech, though as the first word in a sentence until is more common: Until you get that paper written, don’t even think about going to the movies. )
