Could someone help with a little Welsh translation please?

'beth bynnag y gost'

Or 'waeth beth', which means 'no matter what' or 'regardless'

There are many Welsh to English and English to Welsh on line translators, but as always, direct translation of the words is all you will get without any subtleties of meaning or interpretation.

One reasonably good on line translation of “whatever the cost” provides: “whatever 'r chostia” as a direct translation since there appears to be no single word for “whatever” in the Welsh language. But you probably already knew that?

Interpreting the meaning of the phrase as “with no interest in what it takes in time and effort” translates as: “ag na ddiddora i mewn beth chymer mewn pryd a egni”.

I hope that a native and fluent Welsh speaker may be of more help.
