What does lit mean?
“Lit” is a versatile English word whose basic meaning is illuminated or alight. It can describe a room glowing with lamps, candles, or sunlight, and it is also the past tense and past participle of the verb “light.” In informal, particularly American, usage, “lit” has additional meanings: a person may be “lit” because they are under the influence of alcohol or drugs, while an audience or gathering may be “lit” because it is excited, energetic, or enthusiastic. The phrase “lit up” is especially common for describing a place becoming bright or a crowd becoming animated. These informal senses make “lit” more expressive than the plainer “illuminated” in casual contexts, while the standard illuminated sense remains useful in descriptive and literary writing. The word is pronounced the same in British and American English, although the intoxication sense is most closely associated with US usage.

Where does lit come from?
The form “lit” is the past tense and past participle of “light,” a verb meaning to illuminate. “Light” ultimately derives from Old English and Proto-Germanic forms connected with an Indo-European root meaning “shine” or “bright.” Related English words such as “luminous” and “luminance,” though borrowed through Latin, reflect the same ancient root and its associations with light.
