A sermon is an oration by a prophet or member of the clergy. Aspects of preaching incorporate exposition, exhortation as well as functional application. In Christianity, a sermon (likewise understood as a homily within some churches) is regularly given in a site of worship, most of which have a pulpit or rambo, an elevated architectural characteristic.

The word "sermon" originates from a Center English expression which was stemmed from a Former French term, which in turn stemmed from the Latin expression sermo (" discourse"), although links have been made in between the Latin word serene, which indicates 'to join together', so this leaves the contemporary Latin explanation open to model. The phrase can mean "chat", which could well suggest that early sermons were provided in the form of question as well as solution, as well as that only later performed it concern indicate a monologue.
