When /l/ occurs before a vowel, the front of the tongue is raised towards the hard palate; when it occurs before a consonant or in a final position, the front of the tongue is slightly hollowed, and the back is raised towards the soft palate. The former is called “clear I”, and the latter, “dark I”.Glides (滑音)/j/ and /w/ are called glides because each of these consists of a quick and smooth glide towards a following vowel sound.
