Morpholecithus is a scientific term used to refer to a type of egg with a particular arrangement of yolk. It is pronounced /mɔːfəʊlɛˈsɪθəs/ and spelled using a combination of Latin and Greek roots. "Morpho-" is derived from the Greek word for shape or form, while "lecithus" comes from the Latin word for yolk. The "-us" ending indicates that it is a singular noun. Understanding the IPA phonetic transcription can help in pronouncing and spelling complex scientific terms.
