Retreat

To retreat is to move back or withdraw from a place, situation, or conflict, often because of danger or difficulty. As a noun, a retreat can be a quiet, safe place to rest or a planned time away for reflection or training.

From Old French *retret* 'a drawing back', from Latin *retrahere* 'to draw back', from *re-* 'back' + *trahere* 'to pull'. It was first used for armies pulling back from battle.
