Ramisection is a rarely used word in the English language, referring to the branching of a river or stream. Its spelling can be explained using the International Phonetic Alphabet (IPA) as /ræmɪˈsɛkʃən/. The first part, "rami," is pronounced with the short vowel sound /æ/ and refers to a branch. The second part, "section," is pronounced with the long vowel sound /ɛ/ and refers to a division or part. The combination of these two parts creates the unique spelling and pronunciation of "ramisection."
