EtymologyBorrowed from French planification / Spanish planificación. English took the noun without the verb — we have planification but barely planify.
NotePlanning has a planner in it; planification has no doer-slot at all, which is the feature. The -ification pattern this collection kept reaching for is fully alive one language over.
