Origin

The character 郡 combines a sound hint with a geographic classifier. On the left, 君 provides a pronunciation guide—it tells you roughly how to say the character, which is "gun." On the right, the radical ⻏ is a classifier that marks this character as referring to a place or administrative division. Together, the shape brings together the sound of the word for this type of district with a visual indicator that it's a geographical term, creating a character that means county or district.
