Z, or z, is the 26th and last letter of the Latin alphabet, as used in the modern English alphabet, the alphabets of other western European languages and others worldwide. Its usual names in English are zed ('zɛd) and zee ('ziː), with an occasional archaic variant izzard ('ɪzərd).
In most English-speaking countries, including Australia, Canada, India, Ireland, New Zealand, South Africa and the United Kingdom, the letter's name is zed zɛd, reflecting its derivation from the Greek letter zeta (this dates to Latin, which borrowed Y and Z from Greek), but in American English its name is zee ziː, analogous to the names for B, C, D, etc., and deriving from a late 17th-century English dialectal form.
Another English dialectal form is izzard ˈɪzərd. This dates from the mid-18th century and probably derives from Occitan izèda or the French ézed, whose reconstructed Latin form would be *idzēta, perhaps a Vulgar Latin form with a prosthetic vowel. Its variants are still used in Hong Kong English and Cantonese.
Other languages spell the letter's name in a similar way: zeta in Italian, Basque, and Spanish, seta in Icelandic (no longer part of its alphabet but found in personal names), zê in Portuguese, zäta in Swedish, zæt in Danish, zet in Dutch, Indonesian, Polish, Romanian, and Czech, Zett in German (capitalised as a noun), zett in Norwegian, zède in French, zetto in Japanese, and zét in Vietnamese. Several languages render it as ts or dz, e.g. tseta /tseta/ or more rarely tset /tset/ in Finnish (sometimes dropping the first t altogether; /seta/, or /set/ the latter of which is not very commonplace). In Standard Chinese pinyin, the name of the letter Z is pronounced [tsɨ], as in "zi", although the English zed and zee have become very common. In Esperanto the name of the letter Z is pronounced /zo/.
Under the NATO spelling alphabet, the letter is signified with ZULU, like the Zulu people.
The Semitic symbol was the seventh letter, named zayin, which meant "weapon" or "sword".
