A noun in The Etymologies of the 1930s glossed “draught” derived from the root ᴹ√SUK “drink” (Ety/SUK).
Neo-Quenya: This noun may have been replaced by Q. yulda “something drunk, a drink, a draught” (LotR/377; PE17/63), but I think suhto might be retained in reference to “a single act of drinking” vs. yulda for “a drink, the thing drunk”.
A noun in The Etymologies of the 1930s glossed “building, house” under the root ᴹ√KAR “make, build, construct” (Ety/KAR).
