The letters of the Greek alphabet are also used as symbols by mathematicians and scientists. These people pronounce the names of the letters quite differently from Greek people, the 'scientific pronunciation' being very loosely based on the pronunciation of classical Greek.
The table below shows the full Greek alphabet in capital (upper case) and lower case characters. The scientific pronunciation of the letters is shown in the column headed Name in
English; the name of the letter and its pronunciation in modern Greek is indicated in the other two columns.
Note that the capital letters B, H, P, X and Y look the same as letters in the Roman alphabet used in English, but in Modern Greek they are pronounced very differently.
