No common word rhymes exactly with /ˈdɛsəməl/. The six words above share the final /məl/ sound and the spelling '-mal', making them useful spelling and pronunciation companions. However, their stressed vowels are different (e.g., /ɪ/ in 'minimal' vs /æ/ in 'animal'), so do not treat them as perfect rhymes.
