Until vs. unless
by Janice OBrien

Level: intermediate
Age: +8

Online fill-in-the-blank exercise of when to use until vs. when to use unless.


Until   vs.  Unless

Until     O will only occur once X is done (the longer it takes to do X, the longer it will be until O happens. i.e. O happens immediately after X.)
Example 1: He never caught a fish until his father showed him how.  (Once his father showed him how to catch fish [X], he caught one [O].)
Example 2: We can't use the playground until they catch the snake that is out there. (Playing on the playground [O] will not occur until catching the snake [X] occurs.)

Unless    If X is not done, O will not occur. (X may occur anytime before O.)
-------------------------------------------------------------- --> O   (O doesn't happen, because X didn't happen.)
------------------------------X------------------------------ --> O
------------------------------------------------------X------ --> O
----X-------------------------------------------------------- --> O
Example: He never would have caught any fish unless his father had shown him how.  (He would have gone on failing forever -- situation shown on top line -- if he had not been taught how to fish. Sometime after being taught, he succeeded in catching one [O occurred].)
Example 2: We can't use the playground unless they have already caught the snake.  (If X - catching the snake - occurred at some point in the past, then O -- playing on the playground -- can happen.)
