ticle in
the constitution of the language of any particular nation, and must,
therefore, be understood before we can make any progress in learning, or
be able to converse in it. But as this is very complex and tedious to a
beginner, by reason of the great variety of powers the characters, or
letters, are endued with under different circumstances, it would seem
necessary, at least in languages which have never before appeared in
writing, to lessen the number of these varieties, by restraining the
different sounds, and always representing the same simple ones by the
same character; and this is no less necessary in the English than any
other language, as this variety of powers is very frequent, and without
being taken notice of in the following Vocabulary, might render it
entirely unintelligible. As the vowels are the regulations of all
sounds, it is these only that need be noticed, and the powers allotted
to each of these in the Vocabulary is subjoined.

_A_ in the English language is used to represent two different simple
sounds, as in the word Arabia, where the first and last have a different
power from the second. In the Vocabulary this letter must always have
the power, or be pronounced like the first and last in Arabia. The other
power, or sound, of the second _a_, is always represented in the
Vocabulary by _a_ and _i_, printed in Italics thus, _ai_.

_E_ has likewise two powers, or it is used to represent two simple
sounds, as in the words Eloquence, Bred, Led, etc. and it may be said to
have a third power, as in the words Then, When, etc. In the first case,
this letter is only used at the beginning of words, and wherever it is
met with in any other place in the words of the Vocabulary, it is used
as in the second case: But never as in the third example; for this
power, or sound, is every where expressed by the _a_ and _i_
before-mentioned, printed in Italics.

_I_ is used to express different simple sounds, as in the words
Indolence, Iron, and Imitation. In the Vocabulary it is never used as in
the first case, but in the middle of words; it is never used as in the
second example, for that sound is always represented by _y_, nor is it
used as in the last case, that sound being always represented by two
_e_'s, printed in Italics in this manner, _ee_.

_O_ never alters in the pronunciation, i.e. in this Vocabulary, of a
simple sound, but is often used in this manner, _oo_, and sounds as in
Good, Stood, etc.
