An onomatopoeic root with variants ᴹ√TING and ᴹ√TANG appearing in The Etymologies of the 1930s with derivatives ᴹQ. tinge or tango “twang”, ᴹQ. tinga- “to twang”, and N. tang “bowstring” (Ety/TING). The entry had a reference to a deleted variant ᴹ√THING (EtyAC/TING) and another variant ᴹ√TUNG was listed in the entry ᴹ√DING (EtyAC/DING). In the Quenya Verbal System of the 1940s Tolkien gave the root ᴹ√TAÑ as the basis for the verb ᴹQ. tanga- “twang”, which is probably another instance of this root (PE22/103).
