Past tense of 'aim'; directed or pointed something toward a target; intended or planned for a specific purpose or goal.
From Old French 'esmer' meaning to estimate or calculate, ultimately from Latin 'aestimare' (to value). The sense of pointing toward a target developed from the idea of calculating distance and direction.
The connection between 'aim' and 'estimate' reveals that good marksmanship was always about mathematics, not just steady hands. Medieval archers were essentially doing ballistics calculations, estimating wind, distance, and trajectory - making every shot a mini engineering problem.
