The Chinese word 相连 is a compound formed by combining two independent characters: 相, meaning "mutually" or "each other", and 连, meaning "to connect" or "to link". In this combination, 相 acts as an adverbial modifier describing the manner of the action, indicating a reciprocal relationship, while 连 serves as the core verb. Together, they create a single verb meaning "to be connected to each other" or "to be linked together", where the whole meaning is more specific than the simple sum of its parts, effectively capturing the idea of mutual interconnection.
