Where does illuminated come from?

Language of origin: Latin

This word descends from the Latin verb illuminare, meaning 'to light up' or 'to throw light upon', which was built from the prefix in- (here meaning 'upon') and lumen, the Latin noun for 'light'. The same lumen root glows through a whole family of English words, including luminous, luminary, and even the unit of light called the lumen, which is a useful reminder that the middle of the word is spelled with a single m and a single n. English took the verb in through Old French during the late Middle Ages, and by the 1400s it was used both literally, for casting physical light, and figuratively, for shedding light on an idea. A specialised sense grew up around medieval books, where 'illuminating' a manuscript meant brightening its pages with gold leaf and richly coloured decoration. The chief spelling trap is the opening: the prefix in- assimilated to il- before the l of lumin, giving the doubled l of il-lumin, while the rest of the word keeps only single consonants.

How the word is built

• il- (in, upon)
• lumin (light, from Latin lumen)
• -ate (verb-forming)
• -ed (past tense/participle)
