<I think you are forgetting all the mercenaries that joined the Roman
army for a certain time after which many of them went back to their old
place.
<I am sure they had to learn Latin to be able to work as soldiers.
I do not forget them. I just would like to remeber
that the romas were very strict on the componence of the legions.
And they put together the people from the same
region. The iberiasn in legion Iberica, the Italians in legion Italica and so
on
Just wery fe legions were made from mixed people.
If i am not wrong, one of them was Gemina made from two legions.
Moreover the cohortes used to use their own
language and they used they national weapons in fight.
Just the comnader of the cohortes must know latin
language. These are proven facts.
Adn because we know the components of the roman
armie which were in Dacia, this is why there are
questions ( among others).
In Dacia after 118 there were just one Lgeion and
this is Gemina. in 170 ( i guess i a not wrong) the romans brought an another
Legion called Macedonica.
Gemina componence was of mixed people. Iberians,
sirians, italians and so on.
Macedonica wwas with thracians and macedonians
soldiers. If dacians were thracians and their langauge were likely, the soldiers
from theye last legion could understand each other with the dacians in their own
language.
We have no idea about any translator within Dacia.
Bu we have an acheological evidence found in Budapest in old Panonia about a
certain
person who worked as dacain translator . That
means, even there were some dacians around and we learn from the componence of
the panonian legions that the soldiers there were not coming from
thrace..
Is not that easy.. but i guess we will find the
right point one day:))
