October
noun
The kanji for "moon" and "month" are the same, probably because a moon cycle takes approximately a month to occur. So, what is the tenth moon cycle of the year? That would be the awesome month October!
じゅうがつ
This is a jukugo word, which usually means on'yomi readings from the kanji. Since 月 has two on'yomi readings, here's a mnemonic to help you remember which one to use: October gives you jewel guts (じゅうがつ). In October, your guts magically produce jewels, which you collect to make some pretty awesome Halloween costumes.
十月に五十才になります。

十月のシイタケはおいしいですよ。

十月なのにまだビキニ！？
