A hypothetical early root to explain words in the Gnomish Lexicon of the 1910s such as G. fag- “cut” and G. fanc “cut” (GL/33). It might be related to ᴱ√FḶKḶ “cleave, hew”. There are no signs of this root in Tolkien’s later writing.

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.
