happening together
Etymology
'concurrency' originates from Latin, specifically the word 'concurrentia' (from the verb 'concurrere'), where the prefix 'con-' meant 'together' and 'currere' meant 'to run'.
'concurrency' developed from Late Latin 'concurrentia' and Old French/Medieval Latin forms, passing into Middle English as 'concurrence' and later forming the modern English noun 'concurrency'.
Initially it meant 'a running together' or 'meeting together', but over time it evolved into the current senses of 'simultaneous occurrence', technical meanings in computing and geometry, and legal usage for overlapping sentences.
