幸運
こううん
- flat (heiban)
How to read it: a line over a kana means the voice is high there, and ↓ marks where it drops. A kana with no line is low. With no ↓ the pitch stays high to the end and does not drop even on a following particle (が, は).
good luck, fortune
Kōun is probably from Middle Chinese 幸運, literally “lucky fortune”.
Taken apart
Select a part to see every word so far that is taken apart with it.
Wiktionary's text doesn't split this word, so each part is one of its kanji (with the okurigana written after it), with the reading and the dictionary meaning KANJIDIC2 gives that character — a word doesn't always use every sense of its kanji.
In a sentence
幸運を祈るよ。
