Radical 口 · Mouth Radical (mouth, speech, opening)

Semantic Clue (形旁): 口 (indicates that this character is used for speech, sound, or phonetic loan purposes)

Phonetic Clue (声旁): 非 (original sound: fēi)

The mouth radical (口) is placed on the left to show that the character represents a spoken sound or foreign phonetic loan, paired with 'fēi' (非) on the right for the exact pronunciation.

  • 口 Mouth / phonetic indicator
  • 非 Non / wrong / phonetic component providing the sound 'fēi'
Liushu category: Phono-semantic (形声)

Origin: Created as a modern phonetic loan character to transliterate foreign sounds like 'fee' or 'phi' into Chinese, combining the mouth radical (口) to denote speech/sound with the phonetic (非).

Semantic Evolution: Primarily reserved for loanwords and foreign transliterations, most notably in the word for coffee (咖啡).

  • Characters with the mouth radical are frequently deployed to capture non-Chinese phonetic sounds in foreign loanwords.
Sound Shift Bridge: Used universally in modern Mandarin for mapping foreign syllables starting with 'f'.
Vivid Mnemonic Story

You open your MOUTH (口) to drink a cup of coffee, shouting 'NOT (非) decaf!' because you need that strong caffeine hit.

Active Recall Challenge
我每天早上都要喝一杯卡[___]。
Clue: fēi
Common Learner Pitfall

Confusing the standalone character 非 (fēi - not) with 啡 (fēi - used in coffee), forgetting that coffee requires the mouth radical (口) because it is a borrowed phonetic word.

Memory Prompts
