The word "cynancum" is an uncommon term that refers to a type of plant found in the Mediterranean. It is spelled with a "c" and "y" combination, followed by an "n" and "a" to create the "cyan" sound. The final syllable is spelled with a "cu" combination, which is pronounced as "kum." Altogether, the word is transcribed phonetically as /saɪˈnæŋkəm/ in IPA notation. Its unique spelling can be attributed to its Greek origins, which heavily influence spelling and pronunciation in botany.
