An adjective in The Etymologies of the 1930s glossed “thick, fat” derived from ᴹ✶tiukā under the root ᴹ√TIW of similar meaning (Ety/TIW).
Conceptual Development: The Qenya Lexicon of the 1910s had ᴱQ. tiuka “dense, solid” and ᴱQ. tyúka “thick”, both likely derived from the early root ᴱ√TIW̯I (QL/50, 93).
