represent
one
sound,
it is
possible that native would
be
written naitiv, nation
would
be
written naishun,
and
national would
be
written nashunl. However,
English
has
taken another course. English writing
has
another principle
which
governs these cases:
the
morphemic principle.
This
principle states
that morphemes
will
maintain their visual appearance
no
matter
how
their
pronunciations change because
of
phonological processes like assimilation,
palatalization,
vowel
reduction,
and so on.
Although this principle doesn't
always
hold,
it has a
strong consistency.
Given
the
morphemic principle,
we are
still faced with
a
quandary.
Which
of
the
pronunciations
of a
morpheme
is
basic? Which
is the one to
represent
consistently,
if
there
are
alternatives? Certain procedures have evolved
in an-
swer
to
this question.
We try to
maintain
the
spelling
of the
tense
vowel
or
diphthong,
the
"hardest" consonant,
and
include graphemes that
are
pro-
nounced
in
some words
but are
silent
in
other words.

.
To
write
a
morpheme consistently
in
spite
of
variations
in
pronun-
ciation,
the
spelling that represents
a
tense vowel
or
diphthong
is
basic.
Similarly,
always
represent
the
original vowel although
it may
be
"reduced"
to
[a]
with
a
change
of
stress.
Examples:
protest
—
prgtestant
[protest]
[pratsstant]
because
/o/ is
tense
and
/a/
is
lax.
sacrifice
—
sacrificial
[ssekrifays]
[sseknfifl]
2.
We
assume that stops
are
"harder" than
fricatives
and
fricatives
are
harder than
affricates.
Choose
the
stop rather than
the
fricative,
and
the
fricative
rather
than
the
affricate
to
represent
in the
spelling.
Examples:
analog
—
analogy
[aensbg]
[aenaebdsi]
because
/g/ is a
stop
and
/dy
is an
affricate.
physifi
—
physicist
—
physician
[fiziks]
[fizisist]
[fizi^An]
because
the
letter
c
represents
the
stop
/k/
and the
other alterna-
tives
are
fricative
[s] or
affricate
[$].
refrigerate
—
refrigeration
[rsfridssret]
[rsfnd^sre
J
An]
because
/t/
is a
stop
and /
J/
is an
affricate.
depress
—
depression
[dspres]
[dapre
$ An]
because
/s/
is a
fricative
and
/$/
is an
affricate.
