The above words share the spelling ending '-ize'. Except for 'seize', the suffix is pronounced /aɪz/ (or /saɪz/ after voiceless consonants), same as the final /raɪz/ in 'theorize'. However, they do not rhyme with 'theorize' because stress falls on different syllables and the consonant before the suffix differs. 'Seize' is a lookalike: it ends in '-ize' but is pronounced /siːz/, not /saɪz/.
