Morphology
euhedral = eu + hedral
The components are specialised combining forms (eu- and -hedral) uncommon to B1 learners, so the meaning 'having well-formed crystal faces' is not derivable from familiar base words.
Etymology
Euhedral comes from Greek parts eu- meaning 'good' or 'well' and -hedron meaning 'face', as in polyhedron. So a euhedral crystal has 'good faces' — clear, well-formed flat sides.
