To pick up on my previous question a few days ago:
I have to practice somehow, don't I?
I'm afraid I am indeed copying the sentence exactly as written. Here's the paragraph around it:
「彼の頭の中はこの嬢ちゃん と同じですよ。 鳥は大好きな物、うわっついたもの、
フワフワ夢うつつで、未知への期待にいっぱいです。
遠いばかり眺めては鳥の群れに立ち止まる。いつだか急に鳥に夢中になっちまっ
た。あれはどうしてだったかなぁ」
(Regarding the first sentence, there's a little girl present who loves birds as well.)
"Fuwafuwa" is the last thing bothering me about the sentence (and I think we're all familiar with the WWWJDIC). It's mainly the meaning of the "uwattsuita mono" part; to which possible object, the professor or the birds, it and the "yumeutsutsu de" could apply; and the odd, run-on structure that puzzle me.
(Why all the worry about where I got the book? If you're all afraid of me poisoning my pristine mind, I appreciate the concern, but I can assure you it's nothing dirty (and not a doujinshi or anything like that). Really, I don't think anyone's going to run to the library to check out the title, are they?)
I must tell you these sentence in Japanese are not really natural and there are awkward expressions here and there - as ASHIKAGA san mentioned, sounds like translation from English (and rather a poor job).
In translated lieterature it often happens that people use expressions which Japanese native writer would not use even though they are understandable.
This is the very reason ASHIKAGA san asked for more background on the text you're trying to understand.
Whether it is dirty or not is an issue.
To understand these sentences correctly, I need to know many things which are not clear with the sentences or the information you gave.
(1)who is talking these sentence to whom?
(2)彼の頭の中はこの嬢ちゃん と同じですよ。
who is this 彼? (Bird? Professor? You mentioned "the professor" but who is he?)
Who is この嬢ちゃん?
(3)鳥は大好きな物、うわっついたもの、フワフワ夢うつつで、未知への期待にいっぱいです。
This sentence is not correct - it does not make sense.
It can be either
A.鳥は大好きなもの、うわついたもの、未知への期待で頭がいっぱいで、フワフワ夢うつつです。
(It's about a bird, a bird's head is full of its favourite things, flippant things, and anticipation for the unkonwn; the bird is unrealistic day-dreamer.)
[note]
フワフワ is a word to discribe something soft, light, floating air. Figuratively it is opposite to "down-to-earth".
B.鳥は大好きな物。うわっついたもの、フワフワ夢うつつで、未知への期待にいっぱいです。
Birds are (my) favourite. It's something flippant, unrealistic and day-dreaming, and (1) it is full of anticipation (2) it makes me feel the antifipation.
(This is the best I can think of, but because this sentence is grammatically incorrect as the topic part and the description part do not really correspond each other.)
(4)遠いばかり眺めては鳥の群れに立ち止まる。
いつだか急に鳥に夢中になっちまった。
遠いばかり眺めて - obviously the person who translated the English (or any other language than Japanese) into Japanese is not a native because this part is incorrect. Or the person who copied made a mistake and put い instead of く.
遠くばかり眺めては is correct, meaning "looking at a distance".
This sounds like a monologue, reflecting on himself.
Then "Looking at a distance and stop by (when seeing) flock of birds.
Without knowing when but I suddenly got very much attached to birds.
(Though いつだったか and 急に really do not sit well together, but I'm not sure if it is a problem of translation or a problem of the oritinal text.)
(5)あれはどうしてだったかなぁ
This alone means "why that happend" or "why things went like that", a person is wondering why.
But if my interpretation for (4) is correct, this expression sounds very odd to be used on oneself.
I apologize, but I don't understand why the information is necessary. It's the surrounding text that will help with context; the title and author matter only if someone is planning on retrieving a copy of the actual book, which is unlikely. It seems that I'm being asked to prove that the sentence came from an actual book and that I didn't make it up, which is a bit bizarre. I know the sentence is odd; that's why I asked about it here.
The title isn't a secret, and I don't mean to be uncooperative; I just take a bit of umbrage at the intense curiosity into what I'm reading.
In Japanese language, one omits many words/phrase from a sentence when it is obvious in the context.
I took off my hat.
Direct translation word by word is
私は私の帽子をとった。
But unless under a very specific, special situation we do not use pronoun and say
帽子をとった。
instead.
But if one does not know the situation and context, it is very hard to tell who took whose hat.
This means that Japanese is a very much context driven language.
Unless you quote a lot more before these sentences you quoted, nobody can tell correct meaning (or point out the mistakes) of these sentences.
