April
noun
月 in Japanese means "moon" but it also means "month." Why? Probably because the moon takes about a month to get through its cycles. So, what's the fourth moon of the year? Here's a hint, it's the same as the fourth month of the year: April.
しがつ
This is a jukugo word, which usually means on'yomi readings from the kanji. 月 has two on'yomi readings, but it always uses the がつ reading in the names of the months, so here's a mnemonic to help you remember that: In April, you habitually eat sheep guts (しがつ). It's a tradition you started many years ago, and now you just can't stop eating sheep guts every April. Delicious!
四月一日はエイプリルフールです。
April 1st is April Fool's Day.
四月まで、あと三日だ。
Only three more days until April.
四月は、力いっぱいがんばります。
In April, I will try really hard to do my best.
