The phonemic alphabet
A phonemic alphabet is a set of symbols that represent the
sounds of a language. One symbol represents exactly one
phoneme.
Why do we need a phonemic alphabet? It’s because
languages generally don’t have perfect spelling systems, with
exactly one symbol for each phoneme. Sometimes the same
symbol can stand for more than one sound. For example, in
English the letter “c” can represent at least three di"erent
phonemes:
- /k/ as in cat
- /s/ as in city
- /tʃ/ as in cello
In other cases, the same sound can be represented by more
than one spelling. For example, the sound /f/ in English can
be spelled in these ways: - “f” in fun
- “ph” in phone
- “gh” in cough
Because of this, it’s useful to have a special set of symbols
that can represent sounds more consistently. These phonemic
symbols can help both teachers and learners to record and
interpret the pronunciation of new words accurately.
Some of the symbols in the phonemic alphabet of English,
such as /ɡ/ and /ɑ/, look like letters used in ordinary
spelling. However, they don’t always represent the same
sounds that they do in normal spelling, and they can each
represent only one sound. For example, the phonemic symbol
/ɡ/ can represent only the !rst sound in good, not the !rst
sound in gentle; /ɑ/ can represent only the vowel sound in

Phonemic Symbols and Phonetic Symbols
Symbols that represent the phonemes of a language are called
phonemic symbols. We write phonemic symbols with slash
marks around them: /s/. Phonemic symbols represent only the
basic phonemes of the language, not slight variations of them.
Symbols that represent the allophones of the phonemes of a
language are called phonetic symbols. We write phonetic
symbols with brackets around them: [s]. Phonetic symbols are
intended to represent smaller, more exact variations of sound
than phonemic symbols.
When we want symbols to represent actual letters of the
alphabet, we can put them in quotation marks: “s.”
When you write phonemic or phonetic symbols, be careful to
write them exactly as they are. You can’t change from a lower
case to an upper case letter or make other changes in form. For
example, /R/ is a totally different symbol than /r/. Different letter
shapes might also be different symbols; /e/ does not represent
the same sound as /ɛ/; /a/ is not the same as /ɑ/.
