"Impuberal" is a somewhat obscure adjective that describes a state of immaturity or not yet having gone through puberty. Its spelling can be broken down using the International Phonetic Alphabet (IPA): [ɪm-pjuː-bər-əl]. This indicates that the word begins with the short "ih" sound, followed by a stressed "p-yoo" sound, then "buh-ruhl", ending with a soft "uh" sound. Despite its lack of common usage, "impuberal" could prove useful as a more verbose alternative to the more familiar "prepubescent."
