No common English words rhyme exactly with /ˈklɪftən/. 'cliff' shares the initial /klɪf/; 'gift', 'swift', and 'sift' share /ɪft/ but lack the final /ən/; 'button' and 'mutton' share the unstressed /tən/ ending but have different stressed vowels. Do not treat these as rhymes based on spelling alone.
