Llan (placename)
Llan (Welsh pronunciation: [ɬan]) and its variants (Breton:lan; Cornish:lann; Pictish:lhan) are a common placename element in Brythonic languages. In modern orthography, it is treated as a prefix, but was formerly sometimes written as a separate word. The (often mutated) name of the relevant saint or location follows the element: for example "Llanfair" is the parish or settlement around the church of St. Mair (Welsh for "Mary").
