All six words rhyme with the final /neɪl/ of toenail: nail, snail, mail, and hail share the -ail spelling, while whale and pale use -ale with the same sound. Be careful with homophones like mail/male and pale/pail: they sound identical but have different spellings. Also, don't confuse the -oe- in toenail (toʊ) with the spelling of 'does' or 'shoe'; the first syllable is /toʊ/, and the rhyming part is the second syllable /neɪl/.
