Brother is welsh is BRAWD
brawd mawr
You can say "Mae gen i frawd" in Welsh to mean "I have a brother".
You would say "brawd fawr" in Welsh to mean big brother.
If you were trying to say '...my younger brother' - "... Fy mrawd ifanc"
It translates literally from Welsh (Cymraeg) as "little brother", brawd meaning brother, and bach meaning little. Welsh, as in languages such as French, Spanish (and unlike English) follows the noun with the adjective, which would be considered by an English speaker to be inverted.
You can say "Ti yw fy frawd o fam arall" in Welsh, which translates to "You are my brother from another mother."
According to an online Welsh/English translator, it is: caru bob amser brawd i chi.Hopefully, a Welsh speaker will be able to confirm the translation, or to give a correction. There is often several meanings to a word, depending on what context it is used in.
In Irish it's "deartháir" In Welsh it's "brawd" In Scots Gaelic it's "bràthair"
I know for a fact that people in Wales are called Welsh.
even though they are both Welsh and they both have the same Surname I very Highly Doubt they are brothers.
'gyda dy Gymraeg di' is 'with your Welsh'
