Re: What is a "regular (endocentric) thematicization"?

Perhaps a parallel formation in RgVedic may help:

udaka : water.

MWD give the root as ud and notes various various developments of this root such as:

A particle and pre-fix to verbs and nouns.

unatti : to flow to issue out.

udra: a kind of aquatic animal

udric : abound in

udruja : undermining, etc.

ud-ruc: shining forth, etc.

I may be wrong but udrom < ud uuh ( pie derivation) push up from and / or ud-r. start up-rise from> also leading to > ud-arc.

Thanks.

The Wiktionary entry at http://en.wiktionary.org/wiki/war#Tocharian_B for the Tocharian B word for "water" gives a PIE form *udrom as the probable origin for this and states that *udrom is a "regular (endocentric) thematicization".

I could not find out what this means. Does this say that already in PIE there might have been a special form *udrom of the "water" word and say something how that form might have developed?

I traced the info back to the entry for "war" in "A Dictionary of Tocharian B" by Douglas Q. Adams, so it's probably reasonably up-to-date, but that entry does not include more explanation concerning this.

And what is *udrom in the root-suffix-ending scheme? *ud-r-om? With what roles for suffix "r" and ending "om"?
