preachy

The word 'preachy' is a straightforward English formation, combining the verb 'preach' with the adjectival suffix '-y'. The core verb 'preach' entered English via Old French, tracing back to the Latin praedicare, meaning "to proclaim publicly" or "to declare," which itself is a compound of prae- ("before") and dicare ("to proclaim"). While praedicare was used in classical Latin for secular announcements, its meaning narrowed in Ecclesiastical Latin to specifically denote delivering a religious sermon or moral instruction. The adjective-forming suffix '-y', of Germanic origin, is highly productive in English, attaching to nouns and verbs to indicate a quality or tendency. Therefore, 'preachy' literally means "having the quality of preaching," evolving by the 19th century to describe a manner perceived as overly moralistic, didactic, and annoyingly earnest.

Structure: preach (to give moral advice) + y (adjective suffix) preach: From Old French prechier, from Latin praedicare ("to proclaim, declare publicly"). In this word, it functions as the core root conveying the act of moral exhortation. y: A native English suffix (from Old English -ig) used to form adjectives meaning "characterized by; inclined to".
