Etymology: "Oaty" is a straightforward formation: the adjective is built from "oat" with the English suffix "-y", which forms adjectives meaning "having the qualities of" or "characterised by" the base noun. Its base, "oat", traces back through Old English and Proto-Germanic to a much older root, so the suffix is the newer part of the story. The suffix itself has a long pedigree. The "-y" ending descends from Old English "-ig", which the source traces through Middle English "-y" to the form now used in English. In this sense it is the same ending found in "stony", "milky" and "windy", all words that describe a thing by reference to a substance or quality.
