Phonology
Taken from Chapter 4, The Study of
Language, Yule
Phonemes: each one of the meaningdistinguishing sounds in a language
An essential property of a phoneme is that
it functions contrastively. We know there
are two phonemes /f/ and /v/ in English
because they are the only basis of the
contrast in meaning between the words fat
and vat, or fine and vine. This contrastive
property is the basic operational test for
determining the phonemes that exist in a
language. If we substitute one sound for
another in a word and there is a change of
meaning, then the two sounds represent
different phonemes.
Minimal pairs and
minimal sets
Minimal pairs: Phonemic distinctions in a
language can be tested via pairs and
sets of words. When two words such as
pat and bat are identical in form except
for a contrast in one phoneme, occurring
in the same position, the two words are
described as a minimal pair.
Minimal pair:
pat bat
Minimal sets: more than a pair of words.
feat fit fat fate fought foot
the phoneme /t/ is described as a sound
type (in the mind), of which all the
different spoken versions of [t] are
tokens (in the mouth).
Phonology: slash marks are
conventionally used to indicate a
phoneme, /t/, an abstract segment
Phonetics: square brackets, as in [t], used
for each phonetic or physically produced
segment.
Angled brackets <> enclose letters
Allophones: variations of a
phoneme as they are actually
realised
Example:
/t/
Substituting allophones only results in a
different (and perhaps unusual)
pronunciation of the same word.
Allophones are found in:
Free variation: it carries social information
about the speaker
<llueve>
[uebe]
[uebe]
Complementary distribution: it is
determined by the linguistic context
<pin>
<spin>
[pin]
[spin] aspirated /p/
