juncture [Lat. iunctura ‘joint, link’]

In structural phonology, suprasegmental, and distinctive feature, frequently (but not neces-sarily) realized as a pause. Juncture (notation: +) refers to the boundary between two morphemes which, among other things, prevents regular application of phonetic processes which would otherwise occur between two neighboring sounds. With juncture, Good day! is pronounced [gυd+dey], as opposed to [gυdey]. A distinction is generally drawn between open (=realized) and closed juncture. ( also boundary marker)
