Flinch originates from Middle English 'flinchen', which is of uncertain origin but may be related to the Old English 'flencan', meaning to startle or to flinch. The word describes the act of recoiling or drawing back in response to fear or surprise.
Think of someone who 'starts' or 'recoils' when startled — that's why flinch means to draw back suddenly.
