What does circularise mean?
To circularise is to send an identical notice, letter, or document to a large group of people at once, usually to inform them of news, decisions, or forthcoming events. The verb carries a distinctly administrative flavour: councils circularise residents about planning applications, companies circularise shareholders ahead of meetings, and organisations circularise members with agendas or announcements. It is chiefly British in spelling, with American English favouring the variant 'circularize', and it sits comfortably in formal registers where 'send round' or 'mail out' would sound too casual. The word derives from 'circular' in its older sense of a letter addressed to many recipients — itself from Latin 'circulus', meaning a small ring — so its history mirrors the physical practice of distributing identical copies. In an age of mass email and mailing lists, circularising remains a precise term for one-to-many communication, useful when a writer wants to emphasise that a single, uniform message has gone out broadly rather than being tailored to individuals. Its derivatives include 'circularisation' for the act itself.

Before email made it effortless, 'to circularise' was the bureaucratic art of getting one memo into hundreds of hands at once.

Etymology of circularise
Circularise derives from 'circular', which entered English via French from Latin 'circulus', a diminutive of 'circus' meaning ring or circle. The noun 'circular' came to mean a letter or advertisement sent to numerous people at once, and the verb formed on this noun describes the act of distributing such notices. It is thus a cognate of words like 'circle', 'circulate', and 'circuit'. The spelling with '-ise' reflects British orthographic convention; American English generally uses 'circularize'.
