谎话
huǎng huà · HSK 7
lie
谎 (lie) + 话 (speech) = spoken lie; the 言 radical marks it as words
谎 combines the 言 speech radical with 荒 (huāng, wild/absurd) — fitting, since a lie is absurd talk. Pair it with 话 (huà, words) and 谎话 is literally false speech.
话 — speech radical 讠 (言) + tongue 舌
话 is a semantic-phonetic compound. The left side 讠 (simplified from 言, 'speech') gives the meaning, signaling something said, while 舌 ('tongue') hints at the sound and reinforces the speaking sense. The traditional form 話 makes the 言 element explicit; today 话 means 'speech, talk, words.'
