Sermocinator is a rather unusual word in English, with an unusual spelling that can be a bit tricky to memorize. The correct pronunciation is [səˌrmɑːsɪˈneɪtə], with the stress on the second syllable. The first three letters, "ser", come from the Latin word for "speech", while the rest of the word, "-mocinator", is a suffix derived from Latin "monere", meaning "to warn". The base of the word, "sermo", pertains to language and discourse, while "cinator" is a suffix that denotes the agent of a verb, in this case warning or admonishing.
