Sermons are usually, but not always, delivered in a house of worship, most of which have a pulpit or ambo, an elevated architectural feature. A sermon is ... known as a homily within the Catholic Church. The word "sermon" comes from a Middle English word which was derived from an Old French term, which in turn came from the Latin word sermō; ("discourse"). (Actually, it meant "conversation", and early sermons were delivered in the form of question and answer, only later did it come to mean a monologue).
