lunchtime

Synonym discussion
Sense: noun/1
Lunchtime, noon, and midday all refer to the middle part of the day, but they differ in emphasis. Lunchtime specifically names the period when people eat their midday meal, making it the most concrete of the three — you can say 'I'll see you at lunchtime' even on a day when you are not actually eating. Noon is exact and clock-based (12:00 p.m.), while midday is vaguer, covering roughly 11 a.m. to 2 p.m. Lunch hour is the official break allotted for eating at work or school, usually one hour long. In everyday conversation, 'lunchtime' and 'midday' are often interchangeable ('I finish work at lunchtime' / 'I finish work at midday'), but only 'lunchtime' clearly signals a meal break, whereas 'noon' sounds slightly more formal.

Etymology
Lunchtime is a compound word formed from 'lunch' and 'time'. The word 'lunch' probably comes from 'luncheon', meaning a midday snack, which itself may trace back to Spanish 'lonja' (a slice of ham). 'Time' comes from Old English 'tīma', meaning a period or occasion. The compound 'lunchtime' appeared in the 19th century as lunch became a regular midday meal for workers and students.
