'dine-in' originates from the English word 'dine,' which comes from the Old French word 'disner,' meaning 'to eat.'

'dine' evolved from the Old French 'disner' and was combined with 'in' to form the modern term 'dine-in.'

Initially, 'dine' meant 'to eat,' and over time, 'dine-in' evolved to specifically mean eating at the place of service.
