Morphology
octagon = octa + gon
The parts are Greek combining forms ('octa-' = eight, '-gon' = angle) that are not standalone English words, so learners cannot reliably derive 'eight-sided' from the components.
Etymology
The word octagon comes from the Greek parts octa- meaning 'eight' and -gon meaning 'angle' or 'corner'. So an octagon is a shape with 'eight' angles or sides, like a stop sign or the MMA cage, and you can remember octa- by thinking of octopus with eight legs or octave with eight notes.
