proper noun/ka.ʁœ̃/
a surname from Arabic
From Arabic هَارُون (hārūn), pronounced /haː.ruːn/. Doublet of Aaron. The ⟨Kh⟩ digraph is used in this spelling to represent the Arabic /h/ sound; in French, initial ⟨h⟩ is silent, so if this were written Harun, it would end up being mispronounced as /a.ʁœ̃/.
