What is the function of "wedi" in "Dw i wedi blino"? I understand the sentence means "I am tired" but the function of wedi in it fails me. Thanks
wedi means 'after'. dw i wedi blino means literally 'I am after tiring' = I am tired. analogically wedi marw is 'after dying' = dead. there are probably more phrases like that. wedi is also used to form a perfect tense, so dw i wedi blino can also be understood as 'I have tired'.
