to extract, injure
掊 centers on forceful removal or harm: extracting something by hand or causing injury. The two given meanings are connected by the idea of a hand acting destructively or invasively.
掊 combines 扌 (hand) with 咅, which likely contributes the sound. The exact historical development of 咅 is uncertain, but the character is associated with actions done by hand, such as extracting or striking.
The hand radical 扌 beside 咅 suggests a hand forcefully pulling something out or striking. Imagine a hand digging into a wound to extract a splinter, causing injury in the process.
For ホウ, picture a hand holding a hoe (ホウ) to dig out a stubborn root, injuring the soil. The sound of hoe cues ホウ while the hand extracts.
