American spelling: the act or process of eulogizing someone or something; the creation or delivery of a eulogy.
Formed from the verb 'eulogize' plus the nominalization suffix '-ation.' The '-z-' spelling follows American English conventions established in the late 1700s, popularized by Noah Webster.
Noah Webster's dictionary choices literally shaped American English—he favored 'z' over 's' endings because 'z' is more phonetically accurate, and his influence on American schools cemented this difference that persists 200+ years later.
