pronunciation
Pronunciation: /prəˌnʌnsɪˈeɪʃ(ə)n/
noun

Origin:
late Middle English: from Latin pronuntiatio(n-), from the verb pronuntiare (see pronounce)

The word pronunciation is often pronounced, by analogy with pronounce, as if the second syllable rhymed with bounce. This is not correct in standard English: the standard pronunciation has the second syllable rhyming with dunce. The correct spelling is pronunciation, never pronounciation.
