puberty: [14] Latin pūber denoted ‘adult’, and hence, by implication, ‘covered in hair’. Both strands of meaning have followed the word into English: ‘adulthood’ by way of the derivative pūbertās, source of English puberty, and ‘hairiness’ in pubescent [17], which means ‘downy’ as well as ‘having reached puberty’. And the two are combined in pubic ‘relating to the region of the groin where hair begins to grow at puberty’ [19].
puberty (n.)
"the time of life in which the two sexes begin first to be acquainted" [Johnson], late 14c., from Old French puberté and directly from Latin pubertatem (nominative pubertas) "age of maturity, manhood," from pubes (genitive pubertis) "adult, full-grown, manly." Related: Puberal; pubertal.
