蜂巢 (fēng cháo) literally means 'bee nest' — 蜂 (fēng) means 'bee', and 巢 (cháo) means 'nest' or 'lair'. Together, they refer specifically to the hexagonal wax structure built by honeybees to house their colony, store honey, and raise young. Unlike generic terms for animal dwellings, 蜂巢 carries strong biological and ecological connotations and is used in both everyday speech and scientific contexts.

The word evokes images of intricate natural architecture and is sometimes used metaphorically — for example, to describe densely packed, highly organized human-made structures like data centers or apartment complexes. However, its primary meaning remains literal: the physical hive where bees live. It’s neutral in register, appropriate for formal writing, nature documentaries, and casual conversation about insects or beekeeping.
