The Meaning of Dia
Dia (d-ī-ah), or often debated to be pronounced as "Dïa" (d-ee-ah), can be defined as the prefix that was derived from Greek roots, which means "to pass through or join", or defined as "the day" after the word "el día" in Spanish.
Dia (mythology) ("bright sky"), the sister of Callisto in Greek myth.
