Contributed by Daniel Evans
ONE POINT LESSON: GRAMMAR
UNTIL vs. BY
These two words can be very confusing, and many people make mistakes with them. So we need to be careful.
UNTIL:
We use until when we are discussing the amount of time before somthing stops. Basically until means the same as up to the time of.
For example,
-
I will exercise until 5 o'clock.
-
It's OK, I can wait until you finish work.
-
I have until next week to write my report.
BY:
We use by when we are talking about deadlines. Basically, we can use by to mean not later than.
For example,
-
I must run 2km by 5 o'clock.
-
I should finish this project by next month.
-
I will try to have lunch prepared by the time you come home.
-
I will send him an email by next week.
SO REMEMER:
until = up to the time of
by = no later than
