lat. barbatus

Mr. Miguell argued -as I supposed bãiat, bãrbat, bãtran are
maybe the evolutions of the same root- that it cannot be true
because of the :
bãiat>lat. veliatus(?)
bãrbat>lat. barbatus
bãtrân>lat. veteranus
So these 3 words we have to assume they are latin. but we have
still some more
bã> unknow ethymology.
barba
Bart
beard
barbaros

I would like to add here that the roumanians, use for calling
someone who is a male with a short word like "bã, or bãh , bãi
and mã or mãh, mãi". This is not the case for feminine where
they use "fã, or fãh, fãi".
I found out that these words are all refering to male and are
composed with this bã- with some diferent desinences..
bã, bãiat,bãrbat, bãtrân
So, these are the points who made me to think if there is
maybe a common root .
Bãiat:
the rumanians have had a tradition where the new born childern
in the case they were boys, were brought in winter to a river
and submerged into water. The kids who survived, where
considered to be "îmbãiat" from this >bãiat, kinda the one who
survived this bath. One cann argue that this is maybe an
christian tradition, but the word for the christian tradition
is botez, a boteza= to baptise. Îmbãia means to bath and it is
a construction of prefix îm +bãia .The tradition is mentained
today in a christian form where adults swimm in winter into
water for bringing a cross back. So much about what I cann
connect to bãiat.

Bãrbat:
Miguell argued this is a latin word. I know now in Corfu there
is a place caled Barbatus, so we will conclude this is a greek
word. But barbatus/varvatus is not a greek word, this one
beeing from pre-helenic times. I am not so sure but
barbarus/varvarus is kinda likely with barbatus/varvatus sa I
guess somewhere else is the link.

Bãtrân:
I still dont have nothing to corelate with, beside the latin
veteranus.

If there will be a link to find, regarding the bãtrân , then
is for sure they are all the product of the same root.Maybe
even the word barba, beard, Bart are the evolutions of the
same root. Any Ideeas?
