Coming after the fifth in order; number six in a series. It can also mean one part of something that has been divided into six equal parts.
“Sixth” comes from Old English “sixta,” built from “six” plus a suffix that marks order. Both “six” and “sixth” ultimately go back to an ancient Indo‑European root for the number six. English kept a tricky consonant cluster that makes the word hard to pronounce.
“Sixth” is a tiny tongue-twister because English stacked /ks/ and /θ/ together. Many native speakers secretly pronounce it closer to “sikst” in fast speech. So if it feels hard to say, that’s because it actually is, even for locals.
