| 词组 | phth |
| 释义 | phth When this cluster of consonants occurs in words such as in diphtheria, diphthong, or naphtha, the recommended pronunciation is with \\\\fth\\\\, but the most usual version is \\\\pth\\\\. The popular version may even be heard in the speech of specialists: our pronunciation files attest \\\\dip-thäɳ\\\\ from linguists and \\\\dip-'thir-ē-ǝ\\\\ from distinguished doctors. Ophthalmia and ophthalmologist, being rarer words, are more likely to get \\\\f\\\\, but again we have heard \\\\p\\\\ versions even from physicians. (This last-named word presents another trap: we have instances of ophthalmologists and professors of medicine saying \\\\,äf-thǝ-'mäl-ǝ-jǝst\\\\, skipping over the l before the m.) |
