same rule, as 'sporadic', 'dynamic', 'pneumatic', 'esoteric',
'philanthropic', 'emetic', 'panegyric'. As nouns the earlier
introductions threw the stress back, as 'heretic', 'arithmetic',
but later words follow the adjectives, as 'emetic', 'enclitic',
'panegyric'. As for 'politic', which is stressed as we stress both by
Shakespeare and by Milton, it must be under French influence, though
Skeat seems to think that it came straight from Latin.

STEMS IN -OS. These words agree in being disyllabic, but otherwise
they are a tiresome and quarrelsome people. For their diversity in
spelling some can make a defence, since 'horror', 'pallor', 'stupor'
came straight from Latin, but 'tenor', coming through French, should
have joined hands with 'colour', 'honour', 'odour'. The short vowel is
inevitable in 'horror' and 'pallor', the long in 'ardour', 'stupor',
'tumour'. The rest are at war, 'clamour', 'colour', 'honour',
'dolour', 'rigour', 'squalor', 'tenor', 'vigour' in the short
legion, 'favour', 'labour', 'odour', 'vapour' in the long. Their
camp-followers ending in -ous are under their discipline, so that,
while 'cl[)a]morous', 'r[)i]gorous', 'v[)i]gorous' agree with
the general rule, '[=o]dorous' makes an exception to it. All
the derivatives of _favor_ are exceptions to the general rule,
for 'favourite' and 'favorable' keep its long _a_. Of course
'l[)a]b[=o]rious' is quite in order, and so is 'v[)a]pid'.

STEMS IN -TOR AND -SOR. These words, when they came through French,
threw the stress back and shortened the penultimate, _[=o]r[=a]torem_
becoming _orateur_, and then '[)o]r[)a]tor', with the stress on the
antepenultimate. Others of the same type are 'auditor', 'competitor',
'senator', and Shelley has

The sister-pest, congr['e]gator of slaves,

while 'amateur' is borrowed whole from French and stresses its ultima.
Trisyllables of course shorten the first vowel, as 'cr[)e]ditor',
'j[)a]nitor'. Polysyllables follow the stress of the verbs;
thus '['a]gitate' gives '['a]gitator' and 'comp['o]se' gives
'comp['o]sitor'. To the first class belongs 'circulator', 'educator',
'imitator', 'moderator', 'negotiator', 'prevaricator', with which
'gladiator' associates itself; to the second belongs 'competitor'.
Words which came straight from Latin keep the stress of the Latin
nominative, as 'creator', 'spectator', 'testator', 'coadjutor',
'assessor', to which in Walton's honour must be added 'Piscator'
and 'Venator'. On 'curator' he
