Earliest recorded meaning

Köbler's first source is Cicero, whom he dates 81–43 BC.[4]

Semantic evolution

It meant the formation of an idea, a conception, as in Cicero.[2] Lewis & Short add an outline, sketch, first draft, as in Vitruvius' aedium sacrārum īnfōrmātiōnēs “plans of temples”.[5]

In Medieval Latin it meant arrangement, teaching, instruction, and guidance.[6] British Medieval Latin used it for conceiving, shaping, arrangement.[7] Through Old French informacion it gave English information in the late 14th century, “act of informing, communication of news”.[3]
