Sense: verb/1

'Illuminate' (verb/1, LIGHT UP) is the most neutral and versatile term for casting light onto something, suitable for both formal and descriptive writing. 'Light up' is the casual, everyday counterpart and is far more common in spoken English ('The candles lit up the room'). It can also be intransitive, which 'illuminate' cannot ('The sky lit up'). 'Brighten' emphasises the resulting increase in overall brightness rather than the source or act of lighting ('New paint brightened the hallway') and works well for both physical and emotional contexts ('His face brightened'). 'Flood with light' is more dramatic and intense, suggesting a sudden or overwhelming quantity of light ('The morning sun flooded the kitchen with light'). Choose 'illuminate' when you need a precise, slightly formal tone; use 'light up' for natural conversation; pick 'brighten' when the result matters more than the light source.

Etymology

LatinEnglish

From Latin illuminatus, the past participle of illuminare ('to light up, make bright'), which itself comes from in- ('in, upon') and lumen ('light'). The word entered English in the early 1500s with the literal 'light up' sense, and by the late 1500s had developed the figurative meaning of 'enlighten intellectually'. The specialised art-history sense of decorating manuscripts emerged around the same period, rooted in the idea of bringing light and brilliance to the page.
