telma

conclusion, anything used to finish off a work or affair

telma noun "a conclusion, anything used to finish off a work or affair", often applied to the last item in a structure, such as a coping-stone, or a topmost pinnacle (WJ:411). Notice that the form telmanna in the entry TEL/TELU in the Etymologies is a misreading for talmanna (VT46:18) and therefore not the same word as telma.

telmë

telmë noun "hood, covering" (apparently emended from telma, VT46:18); ablative in the phrase telmello talmanna "from hood to base, from crown to foot, top to bottom" (TEL/TELU; the form _telmello t__e_lmanna_ occurring in the Etymologies as printed in LR is a typo, VT46:18)_
