'entry-specific' originates from Modern English, combining the noun 'entry' and the adjective 'specific' (the former from Old French/Latin, the latter from Latin via French).

'entry' changed from Old French word 'entrée' (from Latin 'intrare' meaning 'to enter') and eventually became the modern English 'entry'; 'specific' changed from Latin 'specĭficus' through French 'spécifique' to modern English 'specific'.

Initially, 'entry' meant 'the act of entering' or 'a place of entry' and 'specific' meant 'pertaining to a particular kind'; over time the compound came to mean 'pertaining particularly to a single entry'.
