互相 vs 彼此 (hùxiāng vs bǐcǐ): Understanding 'each other' in Chinese
The key difference is syntactic: 互相 is an adverb placed before the verb, while 彼此 is a pronoun that can serve as subject, object, or possessive. Both express reciprocity, but they occupy different positions in a sentence.
互相 and 彼此 are both used to express reciprocity meaning 'each other' or 'mutually'. The critical distinction is grammatical: 互相 is an adverb that always modifies a verb and appears immediately before it, while 彼此 is a pronoun that can function as a subject, object, or possessive. Therefore, their usage depends on sentence structure: use 互相 before a verb to indicate mutual action, and use 彼此 where a pronoun is required, such as after a verb or in a possessive construction.
When to use each
Use 互相 as an adverb before a verb to indicate that the action is mutual. It cannot be used as an object or subject. Example: 他们互相帮助 (They help each other).
互相 can also appear before certain adjectives used as verbs, e.g., 互相熟悉 (mutually familiar).
Use 彼此 as a pronoun that can be the subject, object, or possessive in a sentence. As an object, it follows the verb. Example: 他们关心彼此 (They care about each other). As a possessive: 彼此的父母 (each other's parents).
彼此 can also be used as a noun in set phrases like 彼此彼此 (same to you).
