What does preach mean?
To preach is primarily to deliver a religious message or instruction, usually from a pulpit or during a service. It can also mean to advocate a belief or moral principle, particularly when the speaker appears earnest, persuasive, or insistent. The phrase “preach the gospel” has a strongly religious and traditional association, while figurative expressions such as “preaching about” often suggest repeated or emphatic advice. In modern informal usage, “preach” may carry the implication that someone is moralizing or telling others how to behave. Historically, the word developed from the Old English term for proclaiming Christian teaching and ultimately relates to Latin praedicare, “to proclaim publicly.” Its continued usefulness comes from its ability to describe both formal religious proclamation and the figurative insistence of a speaker trying to persuade an audience.
To proclaim religious beliefs or moral teachings, especially in a sermon.
"The pastor preached to a large congregation on Sunday morning."
This is the traditional and most common sense. It is used in both British and US English.
To advocate or urge a principle, course of action, or way of life, often persistently or emphatically.
"She was always preaching the importance of honesty."
This figurative sense can be complimentary when the speaker is inspiring, but it is often mildly critical when it suggests moralizing or excessive repetition.
The word that began as a public religious proclamation now often describes the act of delivering a message with relentless enthusiasm.

Where does preach come from?
The word comes from Old English prēcan, meaning to proclaim or announce, especially Christian teaching. It was borrowed into English from Latin praedicare, a compound of prae- and dicere, both meaning “to say” or “to speak.” The same Latin root is reflected in English words such as predict and predicate, and it helped establish the religious sense through which “preach” is now most familiar.
