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.
