A movement made by drawing or striking downwards, often used in writing or drawing.
The artist used a quick downstroke to create the shadow in the painting.
Downstroke → It is formed from "down" (from Old English "dūn", meaning downward or low) and "stroke" (from Old English "strōc", meaning to strike or hit). The word "downstroke" refers to a downward movement or action of striking.
Think of moving "downward" and "striking" — that's what a downstroke means.
