In this paper, an electromagnetic articulography (EMA) study is conducted on four standard Korean speakers to examine their articulation of Korean /l/. Their articulation of /l/ is compared to another sonorant, /n/, in the context of the vowels /a/, /i/, and /u/. Lateralization is quantified by calculating the lateralization angles of both the leftand right-side parasagittal sensors, and retroflexion is examined by observing the angle of elevation seen in the tongue-tip sensor. Considerable intraand inter-speaker variance is observed in the articulation of /l/, with a general tendency for /l/ to be asymmetrically lateralized in coda position, suggesting a lateral approximant articulation. Lateralization appears to be optional in onset position, but the tongue tip is generally raised, indicating a flap, retroflex lateral, or lateral flap articulation. Coda /l/ is also observed to have a tendency to have a raised tongue tip in the context of /a/, suggesting it is a retroflex lateral approximant in this environment.
