呐喊
nà hǎn · HSK 7
shout
📢 both 呐 and 喊 carry the mouth radical 口 — two open mouths roaring out a shout
喊 = 口 mouth + 咸 (xián), which lends the hǎn-ish sound; 呐 = 口 mouth + 内 nà, lending its sound too. Both are phonetic-semantic, so the pair doubles up on mouths to mean shout or rallying cry.
喊 — mouth 口 + 咸 (xián, phonetic)
喊 is a phono-semantic compound. The mouth radical 口 signals it relates to speaking or vocalizing, while 咸 supplies the sound (originally xián, later shifted to hǎn). Together they form the verb meaning 'to shout' or 'to call out'.
