The first (1933) edition of 한글 맞춤법 통일안(han'geul matchumbeop tong'iran) (or 한글 마춤법 통일안) stated that ᇚ should be used in the words 구ᇚ (= 구멍 (gumeong, “hole”)) and 나ᇚ (= 나무 (namu, “tree”)) (see page 17). However, later editions stated that those words are nonstandard (see page 16 of the 1937 edition) or archaic (see page 15 of the 1945 edition), so ᇚ is no longer considered a standard final-consonant digraph. The Hangul Syllables block (U+AC00–U+D7AF) in Unicode does not contain any syllables ending in ᇚ either.
