"Dw i'n gwisgo esgidiau rhedeg."
Translation:I am wearing running shoes.
"Rhedeg" comes from Proto-Indo-European *Hret- (to roll). Thus, it is a cognate of words as diverse as "round" in English, "रथ (rátha)" (chariot) in Sanskrit, and the three following words that mean "wheel": "rueda" in Spanish, "Rad" in German and "rãtas" in Lithuanian.
