‘依附’ is a compound verb meaning ‘to attach oneself to’ or ‘to be dependent on’—often implying an unequal, one-sided reliance where one party gains support, protection, or advantage from another. The character 依 (yī) conveys leaning on, relying upon, or following closely; 附 (fù) means to attach, join, or adhere—like a parasite clinging to a host. Together, they evoke a vivid image of physical or metaphorical attachment, frequently used in biological contexts (e.g., symbiosis or parasitism) and social critiques (e.g., people depending uncritically on authority or wealth).

In modern usage, ‘依附’ often carries a slightly negative or cautionary tone, suggesting loss of autonomy or unhealthy dependence—not mere cooperation or mutual support. It’s common in discussions about ecological relationships (e.g., epiphytic plants or commensal animals), as well as sociopolitical commentary about ideological or economic dependency. Unlike neutral terms like ‘合作’ (cooperate), ‘依附’ emphasizes asymmetry and passivity on the part of the dependent party.
