AA的 / AABB的 (adjective reduplication)

• Pinyin: de
• Formation: AA + 的 (+ Noun) / AABB + 的 (+ Noun)

Meaning

In Chinese, adjectives can be reduplicated to add vividness and emphasis. Monosyllabic adjectives follow the AA pattern (大 → 大大的), while disyllabic adjectives follow the AABB pattern (干净 → 干干净净的). The reduplicated form is usually followed by 的 before a noun.

Adjective reduplication is a distinctive feature of Chinese that has no direct equivalent in English. It adds warmth, vividness, or an appreciative quality to the description, making it more visual and expressive. Not all adjectives can be reduplicated — it works mainly with descriptive adjectives that express tangible qualities like size, color, shape, or emotional states. Monosyllabic adjectives double into an AA的 pattern (大大的, 红红的), while disyllabic ones use AABB的 (干干净净的, 漂漂亮亮的). When the reduplicated adjective modifies a verb, 的 changes to 地 (e.g., 高高兴兴地走). Reduplicated adjectives cannot be further modified by degree adverbs like 很 or 非常.

Examples

1. 她有一双大大的眼睛。 She has big, beautiful eyes.
2. 孩子们高高兴兴地去上学了。 The children went off to school happily.
3. 天空中飘着白白的云。 White clouds drift across the sky.
