luncheon
UK[ˈlʌntʃən]US[ˈlʌntʃən]
n
a formal lunch, or a formal word for lunch
Etymology
The word 'luncheon' originated in the late 16th century, evolving from the obsolete word 'nuncheon', which meant a light snack taken at noon. 'Nuncheon' itself came from Middle English 'nonechench', combining 'none' (meaning 'noon') and 'schench' (meaning 'a drink'). The initial 'n' was lost, and the 'l' was likely absorbed from the word 'lunch', which shares the same root in 'noon'. Over time, 'luncheon' became distinguished from the simpler 'lunch', acquiring a connotation of a more formal or substantial midday meal.
Analysis
This word is a lexicalized whole derived from a longer, obsolete form. It does not segment cleanly into productive morphemes in modern English.
