Typical Greek suffixes.
Primary stress on the third syllable from the end.
(First vowel shown may vary.)
ocracy, opathy, otony, otany, otomy, ophony, ology, onomy,
otrophy, ogamy, ography, ophany, osophy, ognomy, ogony, omaly, opoly, ogeny,
ochrony, ochromy, olatry, omathy, ometry, onymy, oscopy, otropy, ometer, opolis,
anthropy, abola
Also: -ysis, -esis, but NOT -osis.
Instead of the -y ending, these can have -ize (onomize,
opolize), -ous (ogamous, omalous), -ist
(onomist, ometrist), -ism (ologism), or -er (onomer, ographer).
Ex:
democracy, monotony, lobotomy, theology, atrophy, geography,
philosophy, anomaly, monopoly, synchrony, idolatry, trigonometry,
barometer, metropolis, parabola, analysis, synthesis, monopolize, astronomer, photographer
Without the final -y, the stress moves back one syllable. But then it remains on the third syllable from the end.
Ex:
democrat, monotone, catalog, photograph, synonym, telescope
Substituting the adjectival -ic for -y or -sis moves the primary stress
to the second syllable from the end, and may cause other changes (in
consonants).
Ex:
democratic, geographic, philosophic, analytic, synthetic
Secondary stress on the second syllable from the end. The primary stress is earlier in the word.
doxy, plasty, archy, morphy, mony
Ex:
orthodoxy, rhinoplasty, alimony
As above, without final -y, but here the primary stress is on the third
syllable from the end. In effect, the change of removing -y does
not shift the syllable that takes the primary stress.
Ex:
orthodox, oligarch
Primary stress on the second syllable from the end.
osis
Ex:
diagnosis, prognosis
With -ic stress is on the second syllable from the end.
Ex:
diagnostic
