対句

• Reading: ついく
• Romaji: tsuku
• Kanji breakdown: 対 (tai/tsui) — to pair, correspond, oppose; 句 (ku) — phrase, clause, verse
• Pronunciation: /tsɯ.i.kɯ/

Meaning

Couplet; antithesis; parallel construction. A rhetorical device in which two phrases or lines mirror each other in grammatical structure, often with contrasting or complementary meaning.

Central to Chinese-influenced Japanese poetry and prose, particularly in kanshi (Chinese-style poetry), kamubun (Chinese-style prose), and classical Japanese rhetoric. 対句 creates rhythmic and semantic balance. In Chinese regulated verse, 対句 is a strict formal requirement. In Japanese rhetoric, it is used for emphasis and aesthetic effect.
