Nonevacuation is a compound word composed of the prefix "non-" and the noun "evacuation". The prefix "non-" indicates a negative or lack of something, and in this case, it suggests the absence of evacuation. The pronunciation of the word follows the IPA phonetic transcription as /nɒnɪˌvækjʊˈeɪʃən/. The stress falls on the third syllable, and the final sound of the word is -n, not -shun, as it might be assumed from the spelling.
