sud

root. base, ground

stud

root. base, ground

The root ᴹ√SUD “base, ground” appeared in The Etymologies of the 1930s with derivative ᴹQ. sundo “base, root, root-word” (Ety/SUD), but it was given an alternate form ᴹ√STUD with Noldorin forms like {N. sunn >>} N. thund/thonn being added to the entry (EtyAC/SUD). Tolkien’s later of use of S. thond “root” (< ✱stundā?) in S. Morthond “Blackroot” implies the ongoing validity of this root (LotR/1115). In The Etymologies, Tolkien’s first attempt at the basis for “root” words was a deleted entry {ᴹ√NDUM/DUM >>} ᴹ√NDUB/DUB “lay base, foundation, root; found” (EtyAC/NDUB).
