云朵 (yúnduǒ) means "cloud," often with a softer, more poetic or endearing nuance compared to the basic word 云. The addition of 朵 (a measure word typically used for flowers) gives it a gentler, more visual quality, evoking fluffy, distinct cloud shapes. It is common in literary and children's contexts.
