Etymology

Etymology Information

'pre-segment' is formed in modern English from the prefix 'pre-' (from Latin 'prae-', meaning 'before') + 'segment' (from Latin 'segmentum').

Historical Evolution

'segment' comes from Latin 'segmentum' (a cut or piece), from the verb 'secare' meaning 'to cut'. The English noun 'segment' passed through Old French and Middle English into modern English; 'pre-' was attached in English as a productive prefix to mean 'before', producing the compound 'pre-segment'.

Meaning Changes

Originally 'segmentum' meant 'a cut-off piece' (a thing cut), which shifted to 'a part or division' in later usage; combining it with 'pre-' yields the modern specialized sense 'a division made beforehand' or 'to divide beforehand'.
