Morphology

octant = oct + ant

Literally 'eighth part' from the combining form 'oct-' (eight) + '-ant'; the meaning is directly derived but the root 'oct' is a bound combining form rather than a familiar standalone word, so partial transparency for average learners.

Etymology

The word octant comes from the Latin root oct- meaning 'eight', like in octagon. In three-dimensional space an octant is one of eight equal parts, so it simply means 'an eighth part'.
