In an anticipatory manner; in a way that shows expectation about or preparation for something future.
From anticipatory + -ly (adverb suffix). This builds on the adjective form by adding the adverbial marker, creating a four-level word structure from the Latin verb anticipare.
This beautifully unwieldy word shows English's affinity for piling on Latin and Germanic suffixes—anticipatorily has five morphemes stacked together, making it precise but almost comically formal.
