The word amphinucleolus is spelled quite uniquely. Its spelling appears to be a combination of Greek roots, amphi meaning "on both sides" and nucleolus meaning "a small body in the nucleus of a cell". The pronunciation is /æmˌfɪnuːkliːˈəʊləs/, with emphasis on the "kli" syllables. Despite its complex spelling, this term is used in biology to refer to a structure found in the nucleus of some cells. Understanding the IPA phonetic transcription can assist in properly pronouncing and comprehending scientific terminology.
