ᴹQ. Tumbolatsin loc.
A Quenya translation of Tumladen appearing in The Etymologies from the 1930s as a combination of tumbo “valley” and a variant of latina “cleared” (Ety/LAT), perhaps a remnant of the Early Qenya phonetic rule where [ti] became [tsi].
Reference ✧ Ety/LAT
|tumbo||“deep valley (under or among hills, with high sides)”|
|latina||“open, free, cleared (of land)”||✧ Ety/LAT (latin(a))|
