In a way that is perfect, wonderful, or relating to God; extremely well or beautifully.
From Old French 'divin' and Latin 'divinus' meaning godly or heavenly, plus the adverb suffix '-ly'. The word evolved to mean both 'in a godly manner' and 'excellently' in English.
Medieval people used 'divine' to describe anything perfect because they believed only God could be flawless—so calling something 'divinely delicious' was basically the highest compliment you could give!
