会意 · Meaning + meaning

Two or more parts whose meanings together make the new meaning.

The oldest form is an open mouth above a kneeling person: someone receiving an order.

Formal/written for "command, order": 命令 (mìnglìng, order/command), 下令 (xiàlìng, to issue an order), 口令 (kǒulìng, password or drill command).
As a causative verb "to make someone feel X", it's literary register: 令人满意 (lìng rén mǎnyì, satisfying).
In everyday speech, 让 (ràng) or 使 (shǐ) does this causative job instead of 令.
