2indexing radical for characters topped by a flat cap with no roof dot
Tips
usage
冖 is informally called 秃宝盖 ('bald roof') because it looks like 宀 (#40) with the dot shaved off. It heads characters like 写, 军, 农, 冠, 冥 in the Kangxi system.
history
冖 is the proto-form of 幂 (to cover, to drape). The Xinhua entry plainly notes it as 古字, with no independent reading in modern Chinese — mì is the conventional dictionary pronunciation.
Radical
CoverKangxi #14
The flat cover radical. A structural slot for characters topped by a plain horizontal cap (写, 军, 农, 冠). Distinguish from 宀 (roof with dot) and 亠 (lid). Not a standalone word; relevant only as a Kangxi indexing category and as a learner's tool for telling these three caps apart.
