十 (Kanji for ten) | KANJIDAMAGE

Onyomi

JUU	JEWS gave us the ten commandments, the foundation of Western morality.

とう	(also　pronounced just と）meaning, 'ten things'. Yes, it has two pronunciations! JERK ★★★★★

十円(じゅうえん)	ten yen. ★★★★★ 十 (ten) + 円 (yen/circle) = 十円 (ten yen.)
十月(じゅうがつ)	October ★★★★★ FP KANA 十 (ten) + 月 (moon) = 十月 (October)
十日(とおか)	the tenth day of the month ★★★★☆ FP 十 (ten) + 日 (sun, day) = 十日 (the tenth day of the month )
十ヶ月間(じゅうかげつかん)	ten months' time ★★★☆☆ 十 (ten) + 月 (moon) + 間 (a period of time) = 十ヶ月間 (ten months' time) about that little "ヶ" thing - it's pronounced KA, and means "number of months' time". If you take it out, you'd be left with "十月", meaning October. It's the difference between "It's October, the tenth month of the solar year" and "I haven't seen your mom's Ricky Martin sex-tape youtube in a whole ten months!"
二十歳(はたち)	twenty years old ★☆☆☆☆ CCW FP 二 (two) + 十 (ten) + 歳 (years old) = 二十歳 (twenty years old) twenty years old - traditionally the age at which Japanese turn into adults and get presents, kimono, etc. So, naturally it has its own special pronunciation that doesn't make any sense, since it SHOULD be called にじゅうさい。 Whatever. Tradition.
十戒(じっかい)	the ten commandments. ☆☆☆☆☆ FP 十 (ten) + 戒 (admonish / commandment) = 十戒 (the ten commandments.)
