sunlit

Synonym discussion
Sense: adjective/1
All four words describe places that are not dark, but they differ in scope and register. 'Sunny' is the most common and versatile — it is used for weather ('a sunny day'), locations ('a sunny spot'), and even personalities ('a sunny smile'). 'Sunlit' is more specific: it only describes a place that actually receives direct sunlight, never weather or mood. 'Bright' is the broadest term, covering any source of strong light (sun, lamps, even colours), and is very neutral in register. 'Well-lit' focuses on sufficient lighting for a task and makes no claim about whether the light comes from the sun. 'Illuminated' is the most formal and often implies that light is cast onto something deliberately ('the illuminated stage'). Example: 'The sunlit garden was the brightest part of the house; even without lamps it was well-lit for reading.'
Etymology
Formed by combining 'sun' (from Old English 'sunne', the star that gives the Earth light and warmth) with 'lit', the past participle of 'light' (from Old English 'līhtan', meaning to make bright). This compound has been used in English since at least the 16th century to describe places touched by sunlight.
