Lanterning is a rare word that means to stroll around at night, usually while carrying a lantern. If you're looking for alternative terms to use, you might try "nightwalking," "lantern-walking," "moonlighting," or "lamp-lit promenading." Each suggests the idea of taking a leisurely stroll in the evening or night-time hours, with or without artificial lighting. "Nocturnal perambulation" is a more formal way of describing the activity, while "nighttime exploration" might hint at a more adventurous, exploratory aspect. Whatever term you choose, enjoy your lanterning or nightwalking as you take in the peaceful, nocturnal world around you.
