Zeta, a Greek letter that is similar looking to the English letter "z" in cursive. It is the sixth letter of the Greek alphabet but has a numerical value of seven. The letter spawned other letters in other languages such as the Roman "Z" and the Cyrillic 3(Ze), though it was derived itself from the Phoenician letter Zayin. Pronouncing this letter though, has been greatly disputed and its still unsure as to which of the two ways to truly pronounce it. However, most agree on treating the pronunciation as "zd", though some stand firm in attributing the pronunciation like "dz". But however you pronounce it, it is still the same Greek letter, Zeta.
