ᴱ√AKA root. “*intensive, excessive”
A root in the Gnomish Lexicon of the 1910s whose derivatives have to with “extreme” and “excessive“ (GL/17). It’s probably related to the intensive prefix ᴱQ. aka- from the 1920s Early Qenya Grammar (PE14/81). Given the differences in later intensive prefixes and its clash with other roots like 1930s ᴹ√AK “narrow” and (Sindarin only) √AK “hostile return”, it is unlikely this root remained valid in Tolkien’s later conception of the languages.
