na-adjective, noun
elegant speech; smooth-talking; high-sounding
Describes speech that is refined, polished, or superficially pleasant. Rare term; modern Japanese more often uses 口がうまい or 口先だけ.
彼の口綺麗な説明に、みんな騙されてしまった。
Everyone was fooled by his smooth-talking explanation.
na-adjective, noun
not gluttonous; moderate in eating
Rare, possibly archaic sense referring to someone who is not greedy about food. The connection to the first sense is unclear; may be a separate homophonous word.
古い文献では「口綺麗」を「食に淡泊なさま」と説明することがある。
In old texts, 口綺麗 is sometimes explained as 'indifferent to food'.
Refers to lip service or superficial words, often used in 口先だけ.
Compound of 口 (mouth, speech) and 綺麗 (beautiful, clean). The exact origin is uncertain; the second sense may be a separate derivation.
