A noun from The Etymologies of the 1930s glossed “support, prop” derived from ON. tulugme < ᴹ✶tulukmē under the root ᴹ√TULUK (Ety/TULUK).
Conceptual Development: Earlier words of similar meaning include G. talp “prop or support” from the Gnomish Lexicon of the 1910s based on the early root ᴱ√tlp (GL/69) and ᴱN. taichr “prop, support” from Early Noldorin Word-lists of the 1920s derived from primitive ᴱ✶tank’rú (PE13/153). An earlier word of similar derivation was G. taul {“burden” >>} “a pillar” related to G. tul- “†to support” (GL/69).
tulco ("k") noun "support, prop". Given the primitive form ¤tulku, the word would have the stem-form *tulcu*- and the plural form tulqui**. (TULUK)
