Pronunciation of Some Rules of stressed syllables Monosyllabic words automatically take stress For most disyllable nouns, stress is on the first syllables e.g. caput [`keipət] phosphate[`fɔsfeit] For the polysyllables, main stress falls on the antepenultimate syllable (the 3rd syllable of a word counting back from the end) e.g. pathogenesis [7 pæWə`dʒenisis] metabolism [mə`tæbəlism] paralysis [pə`rælisis] Pronunciation of Some Rules of stressed syllables Exceptions: main stress falls on the penultimate syllable (the 2nd syllable of a word counting back from the end) if (1) it has a long vowel and a diphthong ） e.g. magnesium [mæɡ`ni:zjəm] epidermis[7epi`də:mis] prognosis [prɔg'nəʊsis] (2) it is closed by a consonant (including x [ks]) e.g. eclamptism [ek`læmptism] bacillus [bə`siləs] Plural Forms of Medical Terms invariably singular, especially nouns denoting diseases, even though some of them end with –s such as hemophilia arrhythmia adenitis appendicitis arthritis bronchitis diabetes hepatitis measles mumps rickets shingles The Plural forms of some medical words Some medical words may have only the irregular plural forms, for example, bacillus → bacilli, ovum → ova, some may have only the regular forms, for example, virus → viruses, antibody → antibodies, electron→ electrons. Some medical words may have both the regular plural forms and the irregular peural forms, for example, vertebra → vertebras and vertebrae, apex → apexes and apices, matrix → matrixes and matrices, sarcoma → sarcomas and sarcomata， glottis → glottises and glottides, thorax → thoraxes and thoraces. The irregular forms are generally used in formal style, while the regular ones are frequently used in daily medical English, especially in spoken English. Synonymous Phenomenon of Medical Terms different origins Old English, Latin, Greek, French and other languages One result： different elements, or even words are used to refer to the same concept, thing or idea. Overlapping in reference is very common in medical terminology.
