'part-based' originates from the combination of 'part' and 'based', where 'part' refers to a piece or segment of something, and 'based' indicates foundation or reliance.

'Part' comes from the Latin word 'partem', meaning 'a part or division', and 'based' is derived from the Old French 'basse', meaning 'foundation'.

Initially, 'part' meant 'a piece or segment', and 'based' meant 'foundation'. Together, they evolved to describe something that relies on or is structured around parts.
