tôdhi
noun. paddock
A word appearing as G. tôdhi {“fringe” >>} “paddock” in the Gnomish Lexicon of the 1910s based on ᴱ√tadh- (GL/71), probably from ancient ✱tāðī since [[g|[ā] became [ō]]] in Gnomish.
Neo-Sindarin: I would adapt this word as ᴺS. tódhi “paddock” based on the Neo-Root ᴺ√TAD “enclosure”, because while [[os|[ā] became [au]]] in Sindarin, it later [[s|become [ō] or [o]]] in polysyllables. I would assume the final -i was the result of some ancient abstract noun suffix (< ✱tādiyē), much like in S. serni “pebble bank”.
