is the transfer of a word from the letters of one language to the letters
of another, when the written alphabets are not identical.
offers fine examples of this need, for the alphabets are not the same. For
example, the 'B' sound in English is indicated by the letter 'b,' but in Greek
by the letter beta. If typesetters do not have access to a Greek font (or
alphabet), they can, nonetheless, represent the Greek word by transliterating
the word from the Greek alphabet to the English alphabet.
In transliteration, g is written as 'n' before another g. Except in diphthongs,
u is written as 'y.'
