'捡起' is a compound verb meaning 'to pick up', with special emphasis on the physical action of lifting something from a lower position (like the ground) upward into one's hand or grasp. The first character 捡 means 'to pick up' or 'to gather', often implying something small, loose, or discarded; the second character 起 indicates upward motion or initiation of action — together, they stress both the retrieval and the vertical movement involved.

This verb is commonly used in everyday situations involving physical objects: dropping keys, littering, helping someone retrieve fallen items, or cleaning. It carries a neutral, practical tone and appears frequently in spoken and written Mandarin. Unlike the more general 拿 (ná, 'to take'), 捡起 specifically implies the object was previously on or near the ground and requires bending or reaching downward before lifting upward.
