Etymology: The verb "federalises" is the third-person singular form of "federalise," which English built by attaching the suffix "-ise" to "federal." That suffix has an unusually long ancestry: it comes from the Ancient Greek "-izein," which Late Latin adopted as "-izare," and which passed through Middle French into English, where it was already flexible enough to turn almost any noun or adjective into a verb meaning "to make into" or "to make like." The adjective underneath it is the more revealing part. "Federal" traces back to Latin "foedus," meaning "treaty" or "league," a word rooted in the idea of a binding agreement between parties. Over time, "federal" came to describe a union in which separate states keep their own identities while sharing a central government, and that is the sense "federalise" carries: turning independent units into such a union.
