Morphology

ruler = rule (semi-transparent) = rule + er

The word is formed with the common agent/instrument suffix '-er', but the base sense of 'rule' as a measuring standard is less salient than the more common sense 'regulation'.

Etymology

Ruler for the measuring tool comes from the Latin word regula, which means 'straight stick' or 'rule', and shares the same root as the familiar word rule, so a ruler is literally a straight stick used to draw lines and measure length.
