Morphology

heptad = seven (opaque) = hept + ad

Formed from the learned combining form 'hept-' and the suffix '-ad'; these are not productive or familiar to average learners, so the relation to 'seven' is not transparent.

Etymology

Heptad comes from the Greek root hepta meaning 'seven' and the ending -ad meaning 'group'. So a heptad is a 'group of seven', like a seven-sided heptagon or a set of seven people.
