Some loanwords, particularly from classical languages, have the stress on the antepenultimate (third-last) syllable. For example, "fizyka" () ('physics') is stressed on the first syllable. That may lead to a rare phenomenon of minimal pairs differing only in stress placement: "muzyka" 'music' vs. "muzyka" - genitive singular of "muzyk" 'musician'. When additional syllables are added to such words through inflection or suffixation, the stress normally becomes regular: "uniwersytet" (, 'university') has irregular stress on the third (or antepenultimate) syllable, but the genitive "uniwersytetu" () and derived adjective "uniwersytecki" () have regular stress on the penultimate syllables. Over time, loanwords become nativized to have a penultimate stress.
