Tips
usage
挟 literally means to tuck something under the arm, then figuratively to coerce by holding leverage. Common in 要挟 (to blackmail) and 裹挟 (to sweep along by force).
to clamp; to press from both sides (here phonetic-semantic)
Right side 夹 (to clamp from both sides) supplies the sound (jiā drifting to xié) and reinforces the meaning of pressing something tightly under the arm.
