rutslegolas, would you be so kind to give arguments apart from mere statements? thank you

lathspell, thanks for the compliment.

But about Udun and Anor I find it hard to agree (though undoubtedly interesting theory it is). Would Balrog have known names of places which were established after his self-imposed withdrawal to deep places in Moria? (which is to be assumed as happening by the end of the First Age). Besides (form etymologies):

TUB- *tumbu deep valley, under or among hills: Q tumbo, N tum. Cf. Tumladen ‘the level vale’ [LAT], the vale of Gondolin. *tubnā deep: Q tumna lowlying, deep, low; N tofn, Ilk. tovon. *Utubnu name of Melko’s vaults in the North: Q Utumno; N Udun; Ilk. Uduvon; Dan. Utum


ANÁR- sun; derivative of NAR1 . *anār-: Q Anar sun; N Anor.

NAR1- flame, fire. Q nár and náre flame, cf. Anar Sun; narwā fiery red. N naur flame; Anar Sun; narw, naru red. Cf. Egnor [EK], etc.; for Feanor see PHAY. Q narqelion ‘fire-fading’, autumn [KWEL]. [The N form Anar is clear. See ANÁR.]

Gandalf knows Balrog for what it is, and speaks Noldorin names to it. I think the whole passage (and Gandalf's utterances) are another expression of Gandalfs intention to scare Balrog away. He states he knows where it came from (Udun), which is sign of the wise and old spirit (since all moderns refer to it as Durin's Bane not clearly perceiving it for what it is). Than Gandalf states his governance of the power of the Sun, which, whilst first time on the sky scares the guts away from Morgoth and whole his lot.

So, the whole thing might be polite version on:

Remeber how you were afraid of the thing once, you coward? So i can kick you another time, and harder!
