Kundera is a proper noun (a surname, most notably of the Czech-born writer Milan Kundera). It is pronounced with two syllables, stressing the first: /ˈkuːn.dɛ.rə/ (US/UK) or an equivalent two-to-three-beat flow in English usage, adapted to fit natural speech. The name retains its Slavic root consonant cluster but is commonly anglicized in rhythm and vowel quality in English contexts.
