Adjective Reduplication: AA, AABB

Chinese grammar · HSK 2 · 形容词重叠 · By Carson 木林森

Reduplicated adjectives add a sense of vividness, completeness, or affection.

Monosyllabic AA (单音节):
慢→慢慢, 快→快快, 好→好好, 大→大大

Disyllabic AABB (双音节):
高兴→高高兴兴, 漂亮→漂漂亮亮, 干净→干干净净

Uses:
- Adverbial (verb modifier): 慢慢走 (walk slowly and steadily); 高高兴兴地唱歌
- Attributive (noun modifier): 干干净净的房间; 漂漂亮亮的衣服

AA forms often drop the second tone mark in speech (2nd syllable becomes neutral), but written pinyin keeps the original tone. AABB forms typically add 地 before a verb.
