COMPOSITE CONSONANTS

Homogeneous digraphs represent all tensed consonants by putting their base letters side by side (TABLE 1). In contrast to a lax sound (TABLE 3), its tensed sound is a sound with a high tone made by increasing glottal tension at any time of pronunciation process. For example, ㄲ denotes the tensed sound of ㄱ, i.e., [ˀk].
