phonology
Phonology is a branch of linguistics, closely
related to
phonetics,
which studies the manners of organization and usage of the speech
sounds in natural languages. The history of this science reaches ancient
times, as the Greek and Roman grammarians also investigated the
phonological systems of their languages. The foundations for modern
phonological inquiries were laid in the nineteenth century by linguists
such as Ferdinand de Saussure and Henry Sweet. Phonetics deals with
the smallest chunks of
language,
yet it is in connection with other linguistic disciplines like
morphology, because adding morphemes may change the meaning of words and
their pronunciation, frequently following patterns. Phonetics is also
related with
syntax,
as depending on a function of a word in a sentence it can be pronounced
differently with a shifted phrasal stress and with changed intonation.
Similarly, this branch of linguistics is connected with
semantics
because of intonation constraints. While phonetics studies the
production and perception of the speech sounds (for instance, in the
expression 'London photography', phonetics would analyze all the sounds
present in the words 'London' and 'photography', describing how they
are produced), phonology is more interested in the abstract, that is
mental aspects of these sounds. It inquiries into and describes the
patterns of sounds and sound types which native speakers acquire
intuitively. However, since the term 'speech sounds' seems to be used
mainly in phonetics, phonologists speak of phonemes. A phoneme is the
smallest meaningful unit of sound in the human language. Yet it is not
identical with the sound itself, it is rather a theoretical
representation without mentioning its position in a syllable, word, or
phrase (for instance, there are eleven sounds in 'contract hire' but
only nine phonemes). One important feature of phonemes is their
contrastiveness which enables their identification. It is by contrasting
the two phonemes, for example /k/ and /g/ that can be seen that they
differ in at least one feature, like voicing. All languages have a set
of such distinctive phonemes. By and large, it seems that the majority
of languages have about 30 phonemes, but there are some that have as few
as 11 or as many as almost 150. The English language, it is said, has
about 43 phonemes, depending on the variety of English in question. Even
though the number of phonemes may differ from language to language, the
sets are always limited, but enable speakers to create unlimited
numbers of words. In English the word step consists of four phonemes,
and the word pest has the same four phonemes, yet since they are in
different order the meaning is not the same. Phonology also investigates
the possible sequences of phonemes in a given language. Therefore, it
indirectly studies word formation processes, as they too are constrained
by the rules of phonotactics, that is allowable organization of
phonemes. Thus it is very unlikely that any English word should begin
with ng- or the sound /?/ while this sound is quite common in the
middle, or at the end of English words. However, the fact that
phonotactic constraints do not allow for some sounds in a language to
occur in certain positions, which confines the word-coining and word
formation processes of a language, it does not mean that such words do
not appear in that language. Sometimes loan words may break the
phonological rules of a given language and still be in use, as is the
case with the initial position of the / /?n-/ sound in English. By and
large, words with such a sound in the initial position have started
appearing in English only recently and all of them are loan words:
schnapps, schnitzel, schmo. The analysis of the possible sequences of
phonemes is focuses not only on phonemes themselves, but also on
syllables and clusters. A syllable must comprise a vowel, but usually
there is also a consonant (C) before the vowel (V).
Syllables
are frequently described as consisting of an
onset,
which is a consonant, or a few consonants, and a
rhyme,
often subdivided into a
nucleus (a vowel), and
coda
(any following consonants). In the English language coda does not
always have to occur in a syllable, like for instance in the words: he
(CV), or too (CV). Clusters, or consonant clusters are simply two or
more consonants one after another. Clusters, like other phonotactic
rules, are characteristic of a given language, for instance the /st/
cluster in English can be an onset: street, or a coda: highest, however
it is impossible in Japanese. Apart from analyzing the phonemes of a
language, clusters and syllables, phonology also deals with the
processes that occur in everyday, fluent speech. The most frequent
processes that can be observed in casual speech are assimilation and
elision. Assimilation is a process in which certain sounds copy the
characteristics of another, adjacent sound. Elision is a process in
which some sounds, or even syllables are omitted and not pronounced at
all, although in other situations they are normally uttered. Elision
occurs not because of laziness of speakers, but to make the
pronunciation more fluent.
