The word 挨打 (ái dǎ) is a verb-object compound formed by combining the verb 挨 (meaning "to endure" or "to suffer") with the verb 打 (meaning "to hit"). In this construction, the first character 挨 acts as the predicate describing the action of undergoing something, while the second character 打 functions grammatically as its object, specifying what is being endured, namely, a hitting or beating. Together, they create a single lexical unit meaning "to be beaten" or "to take a beating", where the passive or receptive sense is inherent in the meaning of 挨, making the compound semantically distinct from a simple action like "to hit".
