Morphology

straightedge = straight + edge (transparent) = straight + edge

Literal compound of 'straight' + 'edge' meaning an edge that is straight; the tool's purpose matches the literal components.

Etymology

Straightedge combines straight ('not bent') and edge ('side' or 'border'), so it literally means a 'straight side' you can use as a guide. That's why a straightedge is a flat bar used to draw or check straight lines.
