There are no questions about these words, Alex, nor about the origin of
Romanian.
See Rebecca Posner, The Romance Languages, Anchor Books, 1966, pages 83, and
61. It's a standard work, even if it is a bit old now, and it should be
in your university library.
As for your wider question about what Romanian is, I refer you to Giuliano
Bonfante, "the Origin of the Romance Languages" (Winter, 1999) Page 81:
"Romanian lacks all the archaisms which it is easy to discover in the
languages of the West, including languages which have undergone as
far-reaching transformations as French....; Romanian on the other hand
[also] lacks all the Italian innovations later than the second century of
our era .. Romanian is thus the popular Latin of the second century after
Christ; it is neither older nor younger than that date, which is the date
of the colonization of Dacia."
