meet, see
覿 centers on a direct personal encounter: meeting someone face to face or seeing them in person.
覿 combines 見 (see) with 賣, which likely contributes the sound and may relate to the idea of a transaction or exchange, suggesting a face-to-face meeting.
The right side is 見 (see), and the left side 賣 suggests a marketplace exchange. Picture meeting someone in a busy market, seeing them directly among the stalls.
For テキ, imagine meeting a friend at a tech fair: tech -> テキ, and you see each other among the gadgets.
