City radical on the right —
阝 on the right is
邑 (settlement, walled town); on the left it would mean
阜 (mound), so position matters. As
邑-form it indexes
郡 in the family of administrative-place words:
都 (capital),
邦 (state),
郊 (suburbs),
部 (district).
郡 originally meant a commandery, a region administered from a town.
