use of "unless"

hello sir

plzz tell the use of “unless” with examples.

Yogita Nischal



  1. except under the circumstances that: I’ll be there at nine, unless the train is late. I can’t help you unless you are willing to learn.

2. except; but; save: Nothing will come of it, unless disaster. (Note: ‘unless’ is seldom used as a preposition nowadays.)

example: I can’t let you in unless you give the password.

My advice: there are web dictionaries or executable dictionaries which have examples for every single word… The one I used for this example is Cambridge advanced Learner’s dictionary version 3
