Use of の in のために?


Looking at the examples on [WWWJDIC](http://www.edrdg.org/cgi-
bin/wwwjdic/wwwjdic?1Q%B0%D9%A4%CB_1_) for using ために in sentences, I've
noticed that whenever ために can follow a verb without the の particle, while の
must be placed between ために and a preceding noun. For example, 「会社は生活 **するために**
十分な年金を与えた」does not have the の particle, while 「私達は世界の **平和のために** 働いています」does.
However, why is that the case? What function does の perform there?

Right. One usage of the particle **の** is to connect nouns together, very
similar to English 'of'.

> while の must be placed between ために and a preceding noun.  
>  「私達は世界の平和のために働いています」

This の is connecting two nouns, 平和 and ため. It's just the way we Japanese
naturally say things; two nouns cannot be connected without a particle unless
it can be considered as a compound noun.

Like @Felipe Oliveira is saying up there, in the expressions like 昨日のほうが、風のように
also, の is connecting two nouns together: ほう and よう are nouns.

> I've noticed that whenever ために can follow a verb without the の particle,  
>  「会社は生活するために十分な年金を与えた」does not have the の particle,

If you are ready for other usages of の, here, this ため can be replaced with の;
の represents a noun, and makes a phrase or clause right before it a noun, just
like English 'that'.

> 生活する **の** に十分な年金.

It might be more formal with ために than the replacement with の, it's not
necessarily informal either.
