All listed words share the final unstressed /ənt/ sound, but none rhymes with flippant (/ˈflɪpənt/) because the stressed vowel or following consonants differ. Distant (/ˈdɪstənt/) is the closest in stress pattern but has /st/ after the stressed vowel. Beware lookalikes such as tyrant (/ˈtaɪrənt/) and warrant (/ˈwɔːrənt/): their -ant endings are pronounced /ənt/ too, yet the stressed vowels are very different from /ɪ/.
