Pronouncing words like tooth as toof or three as free is a well-known and
long-established feature of Cockney English, but people all over Britain are
now beginning to use ‘f’ for ‘th’, especially adolescent working-class speakers.
How does the change begin, though,
and does it pattern in the same way in different parts of the country? Erik Schleef and Michael Ramsammy
suggest answers to these questions by comparing young people’s speech in
London, England, and in Edinburgh, Scotland, where this pronunciation is a more
recent phenomenon.
Overall, young people in
Edinburgh used ‘f’ pronunciations just as often as their counterparts in
London. In Edinburgh, though – and not in London – ‘f’ was more frequent in
words like maths, where it comes at
the end of a syllable, before another consonant. It was less frequent where it
is followed by a vowel, in words like thin.
Schleef and Ramsammy suggest that these patterns point to the origins of the
sound change. The sounds ‘f’ and ‘th’ share acoustic properties, and this can
make it difficult for listeners to tell them apart in fast speech, especially in
words like maths, when the following
consonant makes them less perceptible.
Confusion of the two sounds
may well explain the origin of the sound change in London too, but here there
has been plenty of time for the use of ‘f’ for ‘th’ to spread to new phonetic
contexts, not just the context where they are most easily confused.
Instead, young people in London
used ‘f’ for ‘th’ more often in morphologically complex words containing more
than one form: words like pathway (path plus way) or months (month plus plural –s). What seems to be happening, Schleef and Ramsammy point out, is
that as the change becomes well-established in a variety of English the
variation becomes increasingly integrated into grammatical word structure. It can
also acquire a social function: in London male speakers use ‘f’ more often than
female speakers, whereas in Edinburgh the variation is too new to be available
for marking gendered ways of speaking.
Will the change follow the
same processes in Edinburgh speech as it has in London, once it becomes more
established, losing the phonetic patterning and becoming integrated into word
structure instead? Not necessarily. Schleef and Ramsammy explain that the sound
system in which the change is embedded differs in the two cities. In Edinburgh
words like thing and think are often pronounced with an
initial ‘h’. Also, a glottal stop is used for ‘th’ in Edinburgh, but only
rarely in London. There is more overall variation, then, in Edinburgh than
there is in London, and this makes it impossible to predict the future of this
sound change.
What is clear, though, is that
comparing social and linguistic influences on a sound change in different
locations can help us understand how a change begins and
how it becomes part of the language system.
