"For" or "Of"

[SomeOne]

And here one more question.
If I ask smb. why is he ignoring something that happening, should I say: What is your..
a) ..reasons OF ignoring smth.
or
b)..reasons FOR ignoring smth.

Can you help me to make out the difference between these two words, please?

PS: It's all about the social survey, so, please, don't pay attention to such a formal construction.

"Of the reasons for ignoring something, which do you consider most appropriate?"

Hope it helps.

Rusty, Heba - thank you both very much!
I think I can see the difference now.
Reasons of smth.
Reasons for doing smth.

Hi, everybody! :)

I have one more question concerning these prepositions. Could you help me to understand, what parts of speech the word "Liking" can be? And according to this, what preposition should be used in such sentences:

Reasons for liking the promo.
or
Reasons of liking the promo.

My dictionary says, that liking is a noun that is similar to sympathy, affinity, etc. Therefore, I should use of with it (if I got everything right) and the 2nd of the sentences above is correct, while the 1st is not. Am I right?

Thanks in advance.

Hello SomeOne: When the –ing form of a verb is used as a noun it is called a gerund.
A gerund can follow a preposition.
Examples: He left without taking his books.
He is good at playing chess.
The question related to your sentences is not whether a gerund can follow a preposition, but rather, what preposition is appropriate after reason.
I have not found any rule about this (maybe others can help here), but I have gone to Google to find which is more common.
Results:
reason for life – 37,300
reason of life – 11,100
reason for *ing – 42,000
reason of *ing – 3,710

Yes, it looks for me like there is no rule about it, but in common speech the "reasons FOR doing smth" version is more general.

And while I can see the difference between "reasons FOR life" (it sounds like "reasons to live" to me) and "reasons OF life" (I think it's similar to the "cause of life"), the difference between "reasons FOR doing smth" and "reasons OF doing smth" is much less obvious for me, if it exists at all.

Anyway, thanks again, Rusty!
