In Spanish dialectology, the terms ceceo, seseo and distinción are used to describe the opposition between dialects that distinguish the phonemes and Ceceo, and those that have merged the two sounds into either (seseo) or (ceceo). Dialects that distinguish the two sounds, and thus pronounce the words casa ("house") and caza ("hunt") differently are described as having distinción, whereas the dialects that lack this distinction and pronounce the two words as homophones are described as having seseo if both words are pronounced with or ceceo if both words are pronounced with . Seseo is typical of the Latin American and Canarian dialects and some dialects of northern Andalusia, whereas distinción is typical of the central dialects of Spain. Ceceo is only found in some dialects of southern Spain.
