One who aims; a person who takes aim or directs something toward a target.
From Old French 'aimer' (to love, to aim), derived from Latin 'aestimare' (to value, estimate). The agent noun '-er' was added to create 'one who aims.'
Before guns and bows, 'aimer' originally meant 'one who loves' because the word came from Latin 'aestimare.' So technically, an aimer is someone who 'estimates' where to point their weapon.
