Morphology
octagonal = octagon (transparent) = octa + gon + al
The adjective is a regular formation from 'octagon' plus '-al', so its meaning is straightforward.
Etymology
Octagonal comes from Greek parts octa- meaning 'eight' and -gon meaning 'angle', the octa- is the same 'eight' in octopus and the -gon is the 'angle' in octagon. So an octagonal shape is one that has eight sides and eight angles.
