服 means clothing as a standalone noun, read ふく. Its other senses include obeying or accepting, performing duties, observing mourning, and taking medicine.
Etymology
This kanji isa phono-semantic compound comprised of 舟 (boat) as the semantic component and 𠬝 as the phonetic component (フク).
Etymology Research
The Chinese University of Hong Kong’s Multi-function Chinese Character Database treats 服 as a later phonosemantic development of 𠬝, an earlier graph associated with subduing and submission, with 凡 subsequently added. It describes some bronze forms as changing 凡 into a 舟-like shape. Qin and Han manuscript forms and the small-seal form retain 舟; the modern classification under 月 reflects a later graphic change. This history gives no reason to interpret today’s left side as the moon or flesh. CUHK, 服
Early uses and proposed origins need separate treatment. CUHK reports 服 as a place name in oracle-bone inscriptions and as an office or duty in bronze inscriptions. Its example from the 班簋 concerns a royal appointment to succeed another person’s office. These attestations do not by themselves prove a clothing or side-boat origin. CUHK also records Lin Jieming’s alternative account of a person presenting a tray in service, with serving as the original meaning. CUHK, 服
Shirakawa Shizuka’s Jitsu instead analyzes the left component as 舟 representing a ritual basin, an early form of 盤, and the right component as phonetic. It proposes a submission or service ritual before the basin and relates this to assigned duties and status. This is a named interpretation, not an agreed reconstruction. It differs from both the side-boat account already on this page and CUHK’s analysis involving added 凡. The accounts agree that the modern 月 shape is inadequate for explaining the character’s origin.
