All listed words share the spelling chunk -ately and the unstressed final syllable /ətli/, but they do not rhyme with alternately (/ˈɔltɝnətli/): its stressed vowel /ɔ/ is followed by /l/, while these words have different stressed vowels and consonants (e.g., separately /ˈsɛp.../, fortunately /ˈfɔːrtʃ.../, ultimately /ˈʌl.../, deliberately /dɪˈlɪb.../). Treat them as spelling lookalikes, not sound matches.
