An odd thing about "neoteric" is that this word for things that are modern and new is itself rather old. It's been part of English since at least 1596, and its roots go back even further - to ancient Greek. We adapted the word from Late Latin neotericus, which also means "recent." "Neotericus" in turn comes from Late Greek neōterikos and ultimately from Greek neos, meaning "new" or "young." As old as its roots are, however, "neoteric" itself entered English later than its synonyms "modern" (which appeared earlier in the 16th century) and "newfangled" (which has been with us since the 15th century).
