pubertal

The word 'pubertal' is a modern scientific adjective derived from the noun 'puberty.' Its core, 'puber,' originates from the Latin puber, meaning an adult or a person who has reached the age of maturity, specifically marked by the growth of body hair (pubes). The suffix '-al,' from Latin -alis, is a standard grammatical tool for forming adjectives meaning "relating to." Therefore, the literal construction "relating to the state of being an adult (sexually mature)" directly informs its modern, precise medical and developmental usage, describing the phase and physical changes of adolescence.

Structure: puber (adult) + tal (adjective suffix) 'puber' is from Latin puber, puberis (adult, sexually mature), referring to the age of physical maturity. 'tal' is an adjectival suffix from Latin -alis, used to form adjectives meaning "of or pertaining to."
