In a question on SO I ran into a question about the meaning of word "closeable". 

As far as I know (and my teachers taught me so) it has two meanings:

* possible to close
* should be closed

The discussion was about whether "closeable" should be used for the resources that *can be* closed, or for those that *should be* closed.

I also searched for imperative forms of "-able", and found some examples, although they're really not so common:

* applicable rules (rules that must be applied)
* marriageable woman (the woman to be married)
* considerable opinion (the opinion everyone should consider)

My questions are: Generally, is the imperative usage of "-able" proper? What does "closeable" mean for a native speaker?


The referenced question on SO: [Java naming convention: isCloseResources() vs doCloseResources?][1]

(Bear with me, I'm not a native speaker. Thanks!)
