Morphology
orthomorphic + projection
If a learner knows the constituent meanings — 'orthomorphic' (preserving true/local shape or form) and 'projection' (a map depiction) — the compound is directly compositional: it denotes a projection that preserves shapes/angles. The adjective+noun combination is literal and non-idiomatic, so the overall meaning is immediately derivable from its parts.
Etymology
Orthomorphic projection comes from old Greek words: ortho meaning 'straight' or 'correct' and morphic meaning 'shape'. So the name describes a map that keeps small areas' shapes and angles 'true', which is why it means a projection that keeps those places looking like their real shape.
