Mayjay is a Japanese-English dictionary. You type a word, then type enter. Mayjay displays definitions. You can type Japanese with kanji or hiragana, or katakana for loanwords. If you do not know kanji, you can type the reading in hiragana, if you know it or can find it (furigana is your friend). You can type English. The JMdict dictionary data that Mayjay displays is biased towards English definitions of Japanese terms, so English-to-Japanese lookups do not always produce useful results. Try a few English synonyms and maybe you will find a good Japanese match.
