(e.g. [s] in Centime, in Cello, in Celsius and [k] in Café). Most of these words are therefore eventually spelt phonetically (e.g. Kaffee, Tschechien (Czech Republic), Zentimeter). Latin words beginning with "ce" such as centum (hundred) traditionally represent in German, and German words derived from these have therefore long been spelt with a Z, which represents (as in Zentrum (centre), Zentimeter (centimetre), etc.). Equivalently, some German speakers pronounce the beginning of the word "Cent" , but since they are familiar with the English pronunciation of the American unit cent, most people pronounce it [s]. As these are nouns, both Euro and Cent are capitalised in German. Slang terms: In Austria and Germany, the euro has also been called Teuro, a play on the word teuer, meaning 'expensive'. The Deutsche Mark was worth half as much as the euro (a ratio of approximately 2:1) and some grocers and restaurants were accused of taking advantage of the smaller numbers to increase their actual prices with the changeover. In youth and Internet culture the fake plural Euronen is sometimes used; this form's origin is unknown but it bears resemblance to Dublonen (doubloons) and has a retro ring to it. Also, "Öre" is occasionally used, the name of the Swedish currency. Unlike the previous currencies (Mark and Schilling) which had well established nicknames for individual coins and notes, there are few widely used nicknames for Euros, but the two Euro coin is sometimes called Zwickel like the old two Mark piece. In German Usenet culture, the name Fragezeichen (question mark) was occasionally used in reference to initial problems with display of the euro sign, which was often rendered as a question mark. The term was most often written using the mock currency code FRZ. This technical trouble has diminished and so has the usage of this term. Abbreviations: EUR. TEUR for thousand Euros and MEUR for a million Euros are often used in financial documents. Numbers are given with a comma as decimal separator. Greek In the Greek language the indeclinable word () is used as the currency's name. It was decided to use omega (ω) rather than omicron (ο) as the last letter of the word, partly because a noun ending with omicron would encourage mutability, and partly to stress the origin of the euro in the Greek word (Eurōpē, Europe) which is also spelt with omega and it is actually written on
