No common word rhymes with stagnant (/ˈstæɡnənt/): its stressed vowel /æ/ plus the following /ɡnənt/ is rare. The final /ɡnənt/ in pregnant (/ˈprɛɡnənt/), indignant (/ɪnˈdɪɡnənt/), and malignant (/məˈlɪɡnənt/) is a genuine sound match for the unstressed ending, but their vowels and stress differ, so they are not true rhymes. Beware the lookalikes elegant (/ˈɛlɪɡənt/) and arrogant (/ˈærəɡənt/): their -gant is pronounced /ɡənt/, without the /n/, and dominant (/ˈdɒmɪnənt/) has -nant /nənt/, without /ɡ/.
