Morphology

mortarboard = mortar + board (semi-transparent) = mortar + board

The compound elements 'mortar' and 'board' are clear, but the sense 'academic cap' is a conventional/cultural extension based on resemblance and not an obvious compositional meaning for all learners.

Etymology

The word mortarboard for the flat square graduation cap comes from a mason's flat tool made of mortar 'paste for bricks' and a board 'flat piece of wood'. The hat looks like that flat board used to hold mortar, so the name moved from the tool to the hat.
