Autrefois

Autrefois is a French adverb meaning "in the past" or "formerly." It denotes a time preceding the present and is commonly used to contrast past conditions with current ones or to evoke a sense of nostalgia. In modern everyday speech, autrefois appears more often in literary, historical, or formal contexts than in casual conversation.

Etymology and form: the word is formed from autre, meaning "other," and fois, meaning "time" or "occurrence." The combination conveys the idea of another time, i.e., a past period distinct from the present. The term has long-standing usage in French and is widely understood across generations.

Usage and nuance: autrefois can introduce descriptions of past customs, social practices, or situations that are no longer typical. It functions similarly to English "formerly" or "in days of old," and is frequently found in historical writing, memoirs, and poetic prose. Common synonyms include jadis and auparavant, while autrefois carries a slightly more literary or reflective tone.
