sermonize

Sermonize is a verb with two related senses. In its primary religious sense, it means to deliver a sermon or to speak in the manner of a preacher, typically offering exhortation or moral instruction to a congregation. More broadly, it can mean to speak at length in a moralizing or admonitory way, often in a way that is perceived as pompous or proselytizing.

Etymology and form: the verb derives from the noun sermon, with the common English suffix -ize. The sense of delivering a sermon dates from early modern English, while its figurative usage—expressing moral admonition—developed later and remains common in colloquial speech.

Usage and nuance: sermonize can carry a neutral or positive tone when describing a religious setting or a formal exhortation. In everyday language it frequently has a negative or critical connotation, implying a long, lecturing, or preachy tone that is unsolicited or unwelcome. The verb can be used intransitively as “to sermonize,” or transitively as “to sermonize someone” or “to sermonize on/about something,” though the latter is less common in casual speech.

Related terms include sermon, sermonette, homily, and moralizing. In contemporary usage, the word often appears in discussions of rhetoric, public discourse, or interpersonal communication, where one speaker is described as sermonizing to another.
