To convert into or reduce to a formula; to express in a systematic or formulaic way (British spelling).
From formula + -ise (British suffix, Latin -izare from Greek -izein). British English uses -ise while American uses -ize for this same verb.
Formularise is the British verb that Americans render as 'formularize'—the -ise/-ize split happened because Noah Webster standardized American spelling differently in 1828, and the Atlantic has kept these parallel version ever since.
