Ewythr is 'uncle' in Welsh (Cymraeg).
Ewythr
t'wara mein
It is "ewythr", but some Welsh speakers have some difficulty pronouncing it, so it is not uncommon to hear "wncl" being used colloquially, especially in South Wales where we tend to be less strict (or formally correct!) with the language.
In Welsh, children typically refer to their grandparents as Nain ("grandmother") and Taid ("grandfather").
I know for a fact that people in Wales are called Welsh.
The Welsh word for "Welsh" is Cymraeg :)
'gyda dy Gymraeg di' is 'with your Welsh'
ymchwil Gymreig = Welsh research ymchwil Gymraeg = Welsh language research
No Welsh equivalent.
'Flicker' is not a Welsh word and has no meaning in Welsh.
The Welsh people Cymry; the language is Cymraeg; the adj. is Cymreig.
