A noun in the Gnomish Lexicon of the 1910s glossed “dale, hillslope” derived from ᴱ√nḷđ (GL/40). Its plural was glidhin, indicating a stem form of glidh-. The ancient initial nḷ- developed into nli- as often happened with favored clusters like nl-, which eventually developed into dl- and then gl-. Meanwhile, the final -dh became -th, though the dh was preserved in the plural form as noted above.
