This rare kanji has no clear standalone meaning. Treat its meaning as uncertain.
The exact historical development of 攟 is uncertain. It visually combines 扌 (hand) with 麕, but the original semantic and phonetic roles are unclear.
Since the meaning is unclear, focus on the shape: a hand 扌 beside a deer-like component 麕. Imagine a hand trying to gather or pick something near a deer, but the exact action is unknown.
For クン, imagine a hand 扌 picking a kun (くん) reading from a rare kanji dictionary: kun -> クン, and the hand is selecting the right sound.
