br>(Joy sweating [暑い], touching hot tea [熱い], holding a thick book [厚い])
“It’s hot today.”
“This tea is hot.”
“This book is thick.”
In Japanese, all of these are pronounced 「あつい (Atsui)」! However, the Kanji is different for each one. Let’s master the three “Atsui” with Joy and Ken.
🗣 Conversation Scene
It is a summer day. Joy is studying at a cafe.
この辞書（じしょ）、厚（あつ）い から重（おも）いです…。
(Phew, it is “hot (weather)” today. This dictionary is “thick”, so it’s heavy…)
コーヒーを買ってきましたよ。まだ 熱（あつ）い から気をつけてください。
(Good work. I bought you coffee. It’s still “hot (object)”, so be careful.)
