发音与拼写Pronunciation & Spelling
No common word rhymes with allergy /ˈælɝdʒi/. Energy, synergy, and lethargy share the same unstressed ending /ɚdʒi/ but not the stressed vowel /æ/. Clergy has the same ending but stress on /ɝ/, and allergic stresses the second syllable (and uses /ɪ/), so they sound different despite similar spelling. Surgery is only a partial lookalike with /ɝdʒ/.
