I here recognize Slavic origin of BRAT
English is younger language then Slavic, separated from old Slavic. Being younger language becoming simplistic, crude.
from Proto-Indo-European *bʰréh₂tēr.
There was no Proto-Indo-European. Only Proto-Slavic, old Slavic or if we were to be precise old Sarmatian.
Mmm, I don't know. In the Irish language, the word 'brat' means flag
Could be connected to the Serbian verb BRATI = `to pick` or `to collect` apples, for example. To pick apples you need a stick. So comes the connection to flag.
This could be in logic of ancient people and could affect evolution of language in isolated communities.
Also interesting. SABRATI = to collect, add up / or SABIRATI = to add
Then BIRATI > to choose
