dinner

The story of 'dinner' is one of shifting time and social ritual. Its core logic lies in the act of breaking a fast, tracing back to the Vulgar Latin 'disjejunare'. In medieval society, the first substantial meal after the morning fast was typically eaten around midday and was called 'dinner'. Over centuries, as social patterns and work schedules evolved, the main meal for many shifted later in the day, pulling the word 'dinner' with it. Consequently, its modern meaning became detached from a specific time, now signifying either the principal meal of the day or a formal evening event, while its etymological cousin 'breakfast' retains the literal sense of ending the night's fast.

The word 'dinner' is a simplex word derived from a single root. It originates from the Old French 'disner' (meaning to dine, originally to break one's fast), which itself came from Vulgar Latin 'disjejunare', a compound of 'dis-' (expressing reversal) and 'jejunare' (to fast), from 'jejunus' (fasting, hungry).
