‘努一努’ is a reduplicated verb phrase meaning ‘to give something a little push,’ ‘to make a small extra effort,’ or ‘to try just a bit harder.’ Though it contains the character 努 (nǔ), which on its own means ‘to exert oneself’ or ‘to strive,’ the full three-character pattern 努一努 adds a gentle, colloquial nuance — suggesting modest, temporary, and often physical effort rather than intense or sustained striving. The ‘一’ (yī) acts as a light quantifier, softening the verb and implying brevity and manageability.

This expression is commonly used in everyday spoken Chinese to encourage someone gently — for example, when helping a child reach a shelf, coaxing a hesitant speaker to begin, or urging a friend to squeeze into a tight space. It carries warmth, patience, and informality, and rarely appears in formal writing. The tone is supportive, not demanding, and the action implied is usually simple, immediate, and physically or mentally minor.
