British spelling: to make academic or scholarly in nature; to introduce academic methods, standards, or approaches to something.
From academic plus the suffix -ise (the British English form of -ize), which creates verbs meaning 'to make' or 'to cause to become.' The suffix derives from Greek -izein through Latin and French.
British and American English split on -ise vs. -ize in the 18th century: Britain kept the older -ise ending (following French practice) while America switched to -ize (following scientific Greek), so 'academise' vs. 'academize' is geography as much as linguistics.
