May
noun
The moon kanji also represents a month, so when you have five of these months, what month of the year is it? That would be May, the greatest month of the year (because it has towel day in it!).
ごがつ
This is a jukugo word, which usually means on'yomi readings from the kanji. If you know the readings of your kanji you'll know how to read this as well. Also, this is a specific month, so it uses the がつ reading.
五月四日にくにへかえりました。
I went back to my country on May fourth.
五月にはゴールデンウィークがあります。
Golden week is in May.
五月に川へいきます。
I’m going to a river in May.
