字源 FORM what the parts do

A foot (止) over the lip of a sunken pit-house (凵): out. Fixed after a verb, 出 hands the verb its one direction; the verb keeps doing what it does, now while leaving an enclosure.

故事 STORY a scene to remember it by

A foot crosses the lip of the sunken pit-house and lands on the open ground outside. The verb is the foot; 出 is the lip it clears.

趨向補語 (進/出 contrast)
出 leaves an enclosure outward; 進 enters one inward. Same gate, opposite crossing.
結果補語
A resultative names an outcome state (看懂); 出 names a direction of travel (走出). One says how it ended, the other says which way it went.
她出走餐廳 ✗ → 她走出餐廳 ✓ (出 follows the verb, never leads it)
她進出餐廳了 (for 'left') ✗ → 她走出餐廳了 ✓ (進 sends the action inward)
她走出去餐廳 ✗ → 她走出餐廳 ✓ (the bare place sits right after 出; 去 attaches only with no place named: 走出去)
English 'walk out OF the restaurant' puts the place after a preposition; Chinese drops the preposition and the place follows 出 directly.
