Different kanji for "akeru" あける：開ける、空ける、明ける

Jim Breen's EDICT doesn't really provide the difference between the three different ways to write "akeru": 開ける、空ける、明ける, so I'm going to write this article for my reference. I hope others will find this useful as well. All definitions come from Kenkyusha's 5th Shinwaei Chuujiten and the Daijiten (研究者新和英中辞典・大辞典) as well.

ものか - rhetorical question

Sample sentence from jisho.org:

二度と恋するなんかものか。
I won't fall in love again.

"used to create a form of question indicating that the speaker actually believes the opposite is true; emphasizes a determination not to do something"

In anime and colloquial speech, you'll probably hear/see this as もんか。
