Prepositions of time "by" and "until" | English lesson

In this English grammar lesson, you will learn how to use the prepositions of time "by" and "until"

In general, "by" + a specific time describes something that must happen before a deadline.

"until" + time expression indicates the duration of a continuous action or event up to a specific moment in time.

I also explain "till" and when we use it.

These prepositions of time are very common and important in English and so, at the end of the video, there is a quiz to test your understanding.
