The prefix presby/o denotes which concept?

Explanation:
Presby/o denotes old age. This prefix is used to describe conditions and changes that come with aging, such as presbyopia (age-related loss of near vision) and presbycusis (age-related hearing loss). It signals old age rather than youth or newborn status, which is why the concept represented is old. Terms for youth or newborn use different roots (juvenile or youth-, neonatal/neonat/o), and while ancient can describe age, presby- is the standard combining form for aging in medical terms.
