Pronunciation & Spelling
All listed words share the common spelling ending -ity and a similar unstressed vowel sound in the final syllable, making them useful for spelling pattern recognition. However, only purity /pjʊˈrəti/ and security /səˈkjʊrəti/ rhyme exactly in General American pronunciation (stressed vowel match as /ʊ/ followed by /r/). Words like sincerity (/sɪnˈserɪti/) have a different stressed vowel (/ɛ/ vs /ʊ/), so they are not perfect rhymes but share the suffix sound.
