发音与拼写Pronunciation & Spelling
Genuine rhymes with porosity: curiosity, generosity, viscosity, ferocity, and velocity all share the stressed /ɒ/ vowel and the following /səti/ (or /sɪti/) ending. Note the spelling difference: porosity, curiosity, generosity, and viscosity use '-osity', while ferocity and velocity use '-ocity'. Posterity looks similar but does not rhyme (its stressed vowel is /ɛ/, not /ɒ/), so do not confuse the two.
