There were 2 things I didn't get in this sentence (or maybe a paragraph...?):

  1. What is the usage of ため in the two appearances of it in the text? (Marked)
    I could tell that it's not the normal usage of ため+に・の and it doesn't makes sense to me as well.
  2. How can this 怪物のうろつく危険な迷宮区画 be translated (literally)? I don't get the spacing in this part... According to the dictionary, the na-adj meaning of 危険 is "danger, peril, hazard"... What I don't get is how exactly "danger" is an adjective? There is another option of "dangerous" in the dictionary, but it wasn't marked as a na-adj meaning. Ignoring the adjective comment I made above, I'd translate it as "A maze area in which there is a danger of roaming monsters" or something like that - but I wanna know why if possible :-)

Thank you in advance!
The sentence above was taken from the novel "Sword Art Online 1"!

As for point 2, probably you should get a better dictionary. – Tsuyoshi Ito Jan 27 '13 at 20:58
@snailplane - Page 10. It's the prologue :) TsuyoshiIto - It's jisho.org... It's the same as well in WWWJDIC – xTCx Jan 27 '13 at 21:01
WWWJDIC has 危険 as dangerous. You are doing pretty well reading this, though, considering you don't realize that some words can be used both as nouns and as na-adjectives. Keep up the good work ;) Also, ため can be used to indicate a cause/reason, that is, it can be translated as "because". Maybe that helps...? – Earthliŋ Jan 27 '13 at 21:05
@user1205935 Looks like jisho.org is formatting edict in a misleading way. The (whatever) before a number belongs to the following sense, not the preceding, but jisho.org puts the line break just before the number. (It also seems to discard the (whatever) before sense #1 entirely on entries like いい加減. Yikes!) – snailplane Jan 27 '13 at 21:09
Bug reported to jisho.org. EDIT: Good news! Kim Ahlström responded to my email saying the bug with jisho.org has been fixed! – snailplane Jan 27 '13 at 22:00

  1. ため can be used to indicate reason/cause. It is always best to check a Japanese dictionary when you can.

  2. The sentence should be parsed as (怪物のうろつく) 危険な迷宮区画, i.e. the sentence 怪物がうろつく modifies (as relative clause) 危険な迷宮区画 (keyword ga/no conversion).

Thank you!! 2 last things though; 1) I'm used to see ため followed by に or の. Why isn't it the case this time? Is it particle omission, or perhaps a usage I'm not aware of...? 2) Makes sense, except the ga/no conversion part... I tried looking for some info about it in google. I found several academic articles about it but couldn't understand much of it and how it relates to this situation... It's probably above my level but I'm a little curious! :D – xTCx Jan 28 '13 at 13:59
nevermind the first... ww8.tiki.ne.jp/~tmath/language/jpverbs/lesson43.htm ni is optional... – xTCx Jan 28 '13 at 14:23
@xTCx For 2) I'm sure there are many academic articles on it, but you can get a long way just knowing that it exists and just think of the sentence with の converted back to が. – Earthliŋ Jan 28 '13 at 21:24
