Maybe I'm being influenced by English here.

In English, demonstrative words typically begin with "th-": this, that, those, the... every time, the "th-" signifies that a reference is made to something already known.

To refer to an already known place in English, you sort of "merge" "th(at)" + "(wh)ere" and get "there"

There is not a combination of that and where.

Old English þær "in or at that place," from Proto-Germanic *thær (cf. Old Saxon thar, Old Frisian ther, Middle Low German dar, Middle Dutch daer, Dutch daar, Old High German dar, German da, Gothic þar, Old Norse þar), from PIE *tar- "there" (cf. Sanskrit tar-hi "then"), from root *to- (see the ) + adverbial suffix -r.

Since in Klingon, {'e'} and {net} also mean a reference to an already-known element (in standard usage, the preceding sentence), and {-Daq} refers to a location (sort of like "where"), putting them together might amount to merging "that + where" as in English, thus getting: (?){'e'Daq} / (?){netDaq} = thereat / there where (the action took place).

I still think it would be a neat way to solve the problem of complex relative clauses in the case of locatives.

But really, maybe it would be best to just ask Maltz, though from what I've seen the chabal tetlh for the next qep'a' is already huge.

We already did ask Maltz, or at least Okrand. He replied that he couldn't get it to work. <http://klingonska.org/canon/1995-06-holqed-04-2-a.txt>
