I am wondering how can we use "can't help it" in a sentence. I want you to explain me it's grammer definition and I would appreciate if you could provide some examples of this expression for me

"can't help it" is, as a phrase, roughly synonymous with "unable to prevent it from happening/being the case" where "it" is an action or habit previously or about to be mentioned.

Here are some examples of its use:

I can't help it if you don't have enough money! (I am unable to prevent the situation where you have insufficient funds for your purchase)

Biting strangers isn't his fault; he can't help it. (He is unable to prevent his compulsion to sink his teeth into people he doesn't know)

This specific sense of help usage is defined by OED as...

help 11a: To remedy, obviate, prevent, cause to be otherwise.
(With can, cannot, or some equivalent.)

It goes back a long way - two of OED's early citations are...

Francis Bacon, 1605 - ...the deficience cannot be holpen (the deficiency can't be helped)
William Shakespeare, 1616 - Cease to lament for that thou canst not help

Note that this usage always requires a negatory context. It's perfectly normal to say I can't help [it, or "doing something"] to mean I'm unable to stop [doing] it, but no-one ever says I can help it to mean they are able to prevent something happening.

Common usages today include...

He can't help it ("it" is usually something undesirable that he can't stop doing)
It can't be helped ("it" is some undesirable situation that cannot be avoided)
He couldn't help laughing (his undesirable action expressed using the continuous verb form)

  • @John: I can't help it if you don't recognize You're not going to get away with that as a "negatory" context! :) Mar 15, 2016 at 17:54
  • I can totally help it. Mar 15, 2016 at 18:33
  • Given enough context, we can both totally say what we like without people thinking we must be non-native speakers. (But they might still think we're totally illiterate! :) Mar 15, 2016 at 18:45
