The linguistic process by which “nuclear” became \ˈnü-kyə-lər\ is called “metathesis,” where two phonemes within a word switch positions.*10 This is the process that gave us the standard pronunciations of “iron” (“EYE-urn” instead of “EYE-run”) and “comfortable” (“KUMF-ter-bul” instead of “KUM-fert-uh-bul”) and other nonstandard pronunciations like “PURR-tee” for “pretty.”
