Oh interesting!  I understand that a preacher covers religious topics, and delivers homilies or sermons to people who are assembled together.
I love listening to our preacher's sermons on Sundays.  How neat to grow up with a pastor as a father.
Hi, how are you? Something interesting about me is my father is a preacher.
A preacher is usually a person who delivers sermons or homilies on religious topics to an assembly of people.
