Director

director, official, govt office, rule, administer

Mnemonic

The director props his elbow on the armrest, raises one finger for silence, then opens his mouth to command: 'Action!' Everyone obeys. Elbow still resting, one eye scanning the set, mouth issuing orders nonstop — this director runs a tight ship.
Additional thoughts
Picture a film director lounging in a chair: elbow planted on the armrest shows relaxed authority, one raised finger demands instant silence, and the mouth delivers every command. The composed posture itself radiates control and oversight.
Quick recall
Elbow on armrest, one finger raised, mouth barking orders — that's the director.
