Here's the breakdown:
* Tydi: You (subject pronoun)
* a: The (definite article)
* roddaist: Gave (past tense verb, 2nd person singular)
So, the direct translation of "Tydi a roddaist" into English is: You gave.
However, the full sentence might have context that makes it more nuanced. For example:
* "Tydi a roddaist fi i mi" could be translated as "You gave me to me", meaning "You gave me to myself".
