The name "Briannah" is a variant spelling of the name "Brianna". The etymology of the name "Brianna" is Gaelic in origin and is thought to be derived from the Irish surname "Ó Briain", meaning "descendant of Brian". It is ultimately derived from the Gaelic word "bre", which means "hill" or "high". The name "Brian" itself is an anglicization of the Old Irish name "Brían", which is believed to have meant "noble" or "high".
