Most pyriform is spelled with the letter combination "pyr" pronounced as /pɪˈraɪ/. The IPA phonetic transcription represents each sound in the word. "Py-" is pronounced as /paɪ/, which is a combination of a voiced bilabial plosive and a diphthong vowel. "-r-" is a voiced alveolar tap pronounced as /ɹ/. The second half of the word "-form" is pronounced with a long "i" sound /aɪ/ and a voiced labiodental fricative "f" /f/. Together, the word "most pyriform" describes a pear shape, with a pronounced narrow end and a wider base.
The term pyriform is derived from the Latin word pyrus, which means pear. It is formed by combining the Latin prefix pyr (meaning fire) and the suffix -form (meaning shape or form). Therefore, pyriform literally translates to pear-shaped.
