发音与拼写Pronunciation & Spelling
The final syllable of sulphate is /feɪt/, matching fate and the ending of phosphate (but not a full rhyme because stress differs). Beware the spellings -feit in forfeit and counterfeit, where it is pronounced /fɪt/, and note that many common -ate words such as private and chocolate reduce the ending to /ɪt/ or /ət/.
