STEMS IN -OSO. These are adjectives and throw the stress back to the
antepenultima, if there be one. In disyllables the penultimate vowel
is long, as in 'famous', 'vinous'; in longer words the antepenultimate
vowel is short, as 'criminous', 'generous'. Many, however, fall
under the 'alias' rule, as 'ingenious', 'odious', while those which
have _i_ in the penultimate run the two last syllables into one, as
'pernicious', 'religious', 'vicious'. A few late introductions, coming
straight from the Latin, retained the Latin stress, as 'morose',
'verbose'.

STEMS IN -T[=O]RIO AND -S[=O]RIO. In these words the stress goes
back to the fourth syllable from the end, this in Latin having the
secondary stress, or, as in 'circulatory', 'ambulatory', even further.
In fact the _o_, which of course is shortened, tends to disappear.
Examples are 'declamatory', 'desultory', 'oratory', 'predatory',
'territory'. Three consonants running, as in 'perfunctory', keep the
stress where it has to be in a trisyllable, such as 'victory'. So does
a long vowel before _r_ and another consonant, as in 'precursory'.
Otherwise two consonants have not this effect, as in 'prómontory',
'cónsistory'. In spite of Milton's

A gloomy Consistory, and them amidst
With looks agast and sad he thus bespake,

the word is sometimes mispronounced.

STEMS IN -[=A]RIO. These follow the same rules, except that, as in
'ádversary', combinations like _ers_ are shortened and the stress goes
back; and that words ending in _-entary_, such as 'elementary' and
