| "Psychiatry" and "psychiatrist" are pronounced with an long "i" and a sound somewhere between "uh" and an unsounded schwa; but "psychiatric" is pronounced with a long "e" and an "a" as in "hat." I haven't come up with any cases sufficiently similar, morphemically speaking, to suggest anything about whether this difference is an instance to a rule or an exception to one. (Closest I can come is geriatry/geriatrist/geriatric, but only the third term is in common enough use to be helpful. "Geriatrician," the vowel-values of which are as per "geriatric," is used instead of "geriatrist," and "geriatrics" is the usual term for what "geriatry" would mean. I'm not sure how we should expect these possible but apparently unused forms to be pronounced.) |
