sharing a common center
Etymology
'concentricity' originates from Latin and Greek roots, specifically from Latin 'concentricus' (from 'con-' + 'centrum'), where 'con-' meant 'together' and 'centrum' (from Greek 'kentron') meant 'center'.
'concentricity' developed from Late Latin 'concentricus' into English via the adjective 'concentric' in Middle English, and eventually formed the modern noun 'concentricity'.
Initially it meant 'being centered together'; over time it has come to mean specifically 'the property or measured degree of having a common center', especially in technical contexts.
