Morphology

concentric = centric (semi-transparent) = con + centr + ic

If a learner knows 'centric', they can partly infer 'sharing a center', but the Latinate prefix 'con-' is not highly transparent for many learners.

Etymology

Concentric comes from con- meaning 'together' and center meaning 'middle'. So, concentric describes shapes like circles or rings that share the same middle point.
