1. An alphabet is a standard set of letters (basic written
symbols or graphemes) which is used to write one or more
languages based on the general principle that the letters
represent phonemes (basic significant sounds) of the
spoken language.
This is in contrast to other types of writing systems, such as
syllabaries (in which each character represents a syllable)
and logographies (in which each character represents a
word, morpheme, or semantic unit).
2. A true alphabet has letters for the vowels of a
language as well as the consonants. The first
"true alphabet" in this sense is believed to be
the Greek alphabet, which is a modified form
of
the
Phoenician
alphabet.).
The alphabet in English has 26 (twenty six)
letters.
