kun-reading homophones (異字同訓)

Sentences containing a word whose kun reading is shared by multiple distinct kanji — the phenomenon called 異字同訓 ('different kanji, same kun reading'). Classic clusters include はく (掃く / 履く / 吐く), とる (取る / 採る / 撮る), あつい (暑い / 熱い / 厚い), こたえる (応える / 答える), はやい (早い / 速い), たずねる (訪ねる / 尋ねる), さがす (捜す / 探す), きく (聞く / 聴く). Kanji choice carries the meaning in writing; context resolves it in speech. Knowing which kanji to use is a reliable measure of writing competence.
