@00dani greek has (or at least ancient greek had, we don't know modern greek in the slightest) several weird consonant clusters like that, like μν (mn, as in mnemonic or amnesia) and φθ (phth, as in phthalate and naphtha)
you learn to pronounce phth if you do any amount of chemistry (it shows up a lot in there) but mn is just usually approximated as /n/
