surname
郄 is a rare kanji used primarily as a surname. Its standalone meaning is unclear beyond that usage.
The historical origin of 郄 is uncertain. It appears to combine ⻏ (a place-related component) with a left side that may have been a phonetic or semantic element, but the exact development is unclear.
Think of 郄 as a family name stamped on a seal: the right side ⻏ suggests a place, and the left side looks like a stylized family crest.
For ケキ, imagine a family named Keki who always bakes a cake for gatherings: Keki -> ケキ, and the cake is their surname tradition.
