> {mo'Dajvo' pa'wIjDaq je narghpu' He'So'bogh SajlIj}

I knew of using {-vo'} and {-Daq} at the beginning of a sentence, in
order to express the "from ---> to"; but somehow I had the idea that
the two nouns can't be joined by the {je}. If this sentence is correct
(is it ?) I will be happy to assimilate this knowledge.

There's no rule against it. There's a theoretical reason not to do it, which is not demonstrated one way or another in canon so far as I know: it might make sense if you cannot stylistically join nouns of dissimilar syntactic roles.

We have seen not conjoining nouns of dissimilar role:

naDevvo' vaS'a'Daq majaHlaH'a'
Can we get to the Great Hall from here? (CK)

(Notice that this sentence seems to violate the later revelations by Okrand of the workings of verbs of motion, like jaH.)

jIH:

> qatlho'qu' voragh ! choQaHta'mo' ghe''orvo' vInarghpu'}
> thank you voragh ! because you helped me, from hell I escaped}

lieven:

> Well, then the place is not the object, so I'd use {jI-} on nargh.

hmm.. I didn't know that. can't {nargh} "to escape" have an object ?
as in "I escaped hell" ?

You can either say ghe''orvo' jInarghpu' I escaped from Grethor or ghe''or vInarghpu' I escaped Grethor.
