躑 combines 足 (foot/leg) with 鄭, which likely contributes the sound テキ. The foot radical suggests a posture or action involving the legs, fitting the squatting and lingering meanings.
The foot radical 足 beside the large 鄭 suggests feet that stay put. Picture someone squatting on their heels, feet planted, loitering in one spot.
For テキ, imagine a tech worker squatting by a server, loitering while waiting for a reboot: tech -> テキ, and the squatting posture keeps them low.
