The word "preclival" is a medical term used to describe the area of the skull located in front of the clivus. Its spelling can be explained using IPA phonetic transcription as "prɛ̆-'klī-vəl", with the stress placed on the second syllable. The "pre" prefix indicates that this area precedes or comes before the clivus, while "clival" derives from the Latin word "clivus", meaning "slope" or "hill", which represents the inclined surface of the skull where it meets the spine.
