ᴹ√STUD* root.* “base, ground”

*root.*“base, ground” - ᴱ√TṚKṚ “*root”

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).
