I am tired of homework.
I am tired with homework.

I am afraid of the dark.
I am afraid withthe dark.
Is there any difference in case of usage?

  • I'm tired of weightlifting = Weightlifting now bores me. I'm tired with weightlifting = The reason I'm physically fatigued is because I've been lifting weights. But that second sense would more often be expressed with from, through, or because of. And I am afraid with the dark is extremely unlikely if not idiomatically invalid in any context. – FumbleFingers Jul 11 '16 at 0:59
  • @ FumbleFingers "I’m dying of thirst" = thrist kills me. I’m dying with thirst= I'm dying because there is no water. – JN Raju Jul 11 '16 at 8:55
  • @ FumbleFingers What about these two : I'm short of money and I'm short in money – JN Raju Jul 11 '16 at 9:39

In each of the cases listed "of" would be used instead of "with".

I am afraid of the dark.

I am tired of homework.

Some examples of "with" would be:

I am busy with my homework.

I met a girl with blonde hair.

Will you come with me?

I eat soup with a spoon.

As a student of other languages, I can easily see why this is so confusing, but it is not so much an issue of the rules grammar as it is an issue of definition of words. The word "of" has a myriad of meanings as is the case with several prepositions. They are connecting words. As such, they are highly adaptable. http://www.merriam-webster.com/dictionary/of

  • Your examples are correct, but you don't explain why "of" should be used instead of "with". 'I'm bored with homework' or 'I'm bored of homework' - how do I use your answer to figure out which one is correct? Why "busy with" but "tired of"? – ColleenV Jul 10 '16 at 23:08

    @ColleenV, adjective + preposition combinations (like afraid of) and verb + preposition combinations (like eat with) are common in English, but unfortunately there is no real system to which preposition goes with which adjective/verb. You can find lists of common combinations if you google, but you basically just need to memorize them. – 1006a Jul 11 '16 at 0:47
  • @nedibes That's right - and that information should be in an answer if it is to be complete. – ColleenV Jul 11 '16 at 11:30
