Norodom Sihanouk refers to the Cambodian royal figure who led Cambodia in various political roles across the mid-to-late 20th century. It is a proper noun used as a name, and here it is treated as a compound proper name with alternating given and family names. Note: the phrase is not a verb in standard usage; if you encounter the name in political titles, pronounce with Cambodian phonology, stressing the given-name syllables distinctly.
