Morphology
gonal = gon + al
Built from the bound combining form 'gon' (angle) + the adjectival suffix '-al'; because 'gon' is not a standalone English word and is mainly technical, many learners will need knowledge of related words (e.g., polygon, hexagon) to infer the meaning.
Etymology
Gonal comes from an old Greek root gon meaning 'angle'. You can see the same root in hexagon and polygon, so gonal in a word tells you it has a certain number of 'angles' or 'sides', which is why a hexagonal tile has six sides.
