autumn
JLPT4 G2 S9 F635
The relevant oracle bone form of this character is 禾 grain/rice + 束 bundle → bundle and compact/shrink harvested crops in *autumn*/*fall*. The character was later reinterpreted, as shown by a seal inscription form that is 禾 plus an element combining 火 fire and 龜 turtle → dry and shrink the size of harvested crops (as turtle meat is dried over a fire; compare 焦). The present form repositions 禾 and 火 while eliminating 龜. Note also the variant form 龝, which combines 禾 and 龜.
