I don't have a dictionary and I use Japanese-English Dictionary Interface (JEDI). It's good but of course doesn't narrow down enough my searched words.
You say find a good website, but this is easier said than done. Have you any suggestions?
Yes I'm taking a class but no, a dictionary isn't a prerequisite since the text book we're using has most of the definitions we encounter in the class and we learn lots of new words every week.
A dictionary would be useful which is why I'm now getting one.
On the computer, the cheapest, best thing you can do is download EDICT, a fairly large open source J-E dictionary. EDICT can be used with various front-ends -- I use JWPce. It can also be used on the Internet via WWWJdict (or something like that).
Thanks for the help. I've started to use EDICT online and I'm impressed! I'm just popping out during my lunchtime to find a paper dictionary as well that I can browse on the train... Thanks again all!
I personally prefer jisho.org for an online dictionary. You can search English words as well as different kanji and words/phrases. I find it particularly helpful because it separates them into their core words and it's really good at finding inflections of verbs.
