As for the comment in Notes, t should be にくい, not いくい. typo?
In kanji 'にくい' is in 難い or 悪い
'verb conjugation + にくい'.

Miki

fixed, thanks!

What's the difference between むずかしい and にくい?

Hey groove in your second example. I don`t think you need the する.

思い出す is a verb already. other than that I like your explaination very clear I added a vocabulary note for yasui

tigert

The different is that 難い is added to a verb stem to change it to an adjective, whereas 難しい is an existing adjective meaning 'difficult', and thus can't be conjugated to a verb stem.

For example:

That word is difficult to remember (lit. That word's remembering is difficult.)
その言葉が思い出し難いな。

as compared to:

Remembering that word is difficult (lit. That word's remembering is difficult).
その言葉は思い出すことが難しいだ。

EDIT 10/15/07: You're right; thanks tiger!
