A meal that is eaten in the middle of the day, often more formal than a regular lunch.

**Luncheon** → It originates from the word 'lunch' (which is a diminutive form of 'luncheon' in Middle English, meaning a light meal) combined with the suffix '-eon' (a diminutive suffix). The word 'luncheon' refers to a light meal typically eaten in the early afternoon.
Think of 'lunch' as a light meal, and remember that 'luncheon' is just a more formal way to refer to a light meal in the afternoon.
