The word 修补 (xiūbǔ) is a compound verb formed by combining two semantically similar characters: 修 (xiū), which means "to repair" or "to mend", and 补 (bǔ), which means "to patch" or "to supplement". This is an example of a coordinative compound, where the two elements are closely related and reinforce each other to create a more comprehensive meaning. Together, they form a single concept meaning "to mend and patch up", specifically referring to the act of repairing something by fixing and restoring its damaged parts, as in repairing clothes, objects, or even relationships.
