Taken at noon, the midday meal was known as 'lunch' or 'dinner'. The name largely depended upon social background, but is was also dictated by the function of the repast. In a working-class family, the meal was referred to as 'dinner' and, in cases where a man could return home from work at this hour, it was the family's main meal of the day... Among middle-class families, the midday meal was generally called 'lunch'or 'luncheon', to give it it's full title.
On a typical weekday in 1837, an agricultural labourer's wife living in the south-east of England... would have offered her family a simple serving of a few slices of bread for the evening meal, which was known as 'supper'... In the home of a skilled tradesman such as a carpenter or blacksmith in almost any market town of England or lowland Scotland, the main meal of the day would have already been taken at midday. The evening meal, whether it was called 'tea' or 'supper', was based upon bread and butter... The fashionable middle and upper classes sat down to dine at five o'clock in the evening. They may have partaken of lunch, or tea and cakes, earlier in the day, but this was their primary mealtime, and they called it 'dinner'.
