Morphology

heptagon = hepta- + -gon (semi-transparent) = hepta + gon

The structure follows the regular pattern for polygon names and learners familiar with names like 'hexagon' can infer the meaning, but the components are bound combining forms rather than standalone English words.

Etymology

Heptagon comes from the Greek parts hepta 'seven' and -gon 'angle', the same idea you see in the familiar octagon. So a heptagon is a flat shape with seven sides and seven angles.
