agreement, consent, comply with
JLPT2 G7 S8 F1813
A variant form of 肎 ( 冖 cover + 肉 flesh), indicating an arm hanging from a shoulder (compare 肩) and covering the side of the body. *Consent*, *agreement* and *permission* are borrowed meanings. In Old Chinese, neither 冖 nor 肉 conveys the pronunciation of this character, suggesting that a) one (or both) of the original components differed or b) one functioned as an abbreviated form of a now-obsolete character.
