preach
Preach is a one-word reply that means you strongly agree with what someone just said, like an amen. It is friendly support unless it answers something absurd.

What it means
When someone replies "preach" to your post or text, they are agreeing with you, loudly. It carries the sense of "keep saying that", "you're speaking the truth" or "that needed to be said", the way a congregation urges a preacher on mid-sermon. It usually answers an opinion, a complaint, a political point or a shared experience. The University of South Carolina's Cocky Talk Dictionary defines the interjection simply as "to agree", with the example "preach my brother", and Slang.org calls it an exclamation of agreement or affirmation, used as a word of encouragement. It turns sarcastic when it answers something the replier obviously does not buy: a brag, a wild exaggeration, a hypocritical take. Then it means roughly "sure, keep telling yourself that". The comment it replies to is the best clue. "my landlord raised the rent again with zero notice" followed by "preach" is support. "I never do anything wrong, everyone else is too sensitive" followed by "PREACH!!!" is much more likely a jab. Capitals and stacked exclamation points make either reading louder. It is informal. It fits a group chat or a casual Slack channel; in an email or a report, "I agree" or "well said" does the same job. Anyone can say it, and its roots in Black church call and response are worth knowing, since exaggerating a preaching voice to be funny can come across as mocking the tradition it came from.

How to use it
“preach”
A one-word reply under an opinion or a complaint. Plain agreement.
“preach girl, say it louder”
Agreement aimed at a friend, pushed a little harder for emphasis.
“PREACH!!! yeah you never do anything wrong”
Answering a brag or a wild claim. The caps and the follow-up turn it into sarcasm.
“he keeps preaching at me about my sleep schedule”
The ordinary verb, used about someone lecturing. This one is a complaint.
Where it came from
The agreement sense grew out of call and response in Black church preaching, where the congregation talks back to the preacher to encourage the sermon along. In "The 'Miracle' of Black Preaching", published in Christianity Today on January 30, 1976, James S. Tinney lists "Preach" among the phrases a congregation inserts, alongside "Yes, Lord", "So true", "Break it on down" and "Take your time". Charles E. DeBose's chapter "African American Church Language" in The Oxford Handbook of African American Language (2015) describes the same tradition, including call and response and a continuum running from sacred church language into secular everyday speech.
From church, the one-word reply moved into everyday African American speech and then into comment sections and group chats, where it is used for any point worth backing. No single coiner is documented, and no single song, show or post is recorded as the moment it spread. Gen Z uses it widely today, and it was a congregational response decades before TikTok existed.
The verb itself is centuries old. The Online Etymology Dictionary traces preach through Old French to Late Latin praedicare, "to proclaim publicly, announce".
No single person is credited, the origin is commonly reported.
