Correct spelling for the English word "Exauguration" is [ɛɡzˌɔːɡjʊɹˈe͡ɪʃən], [ɛɡzˌɔːɡjʊɹˈeɪʃən], [ɛ_ɡ_z_ˌɔː_ɡ_j_ʊ_ɹ_ˈeɪ_ʃ_ə_n] (IPA phonetic alphabet).
The word "exauguration" is not commonly used in the English language, and it does not have an established etymology. It appears to be a neologism or a rare coinage, possibly formed by combining the prefix "ex-" (meaning "out" or "from") with the word "inauguration" (referring to the formal beginning or initiation of something). As such, "exauguration" could be interpreted to mean the act of removing or terminating an inauguration or the conclusion of a formal initiation. However, due to its limited usage, it is advisable to verify the intended meaning within the context of its specific usage.
