gerontological

The word 'gerontological' is a modern scientific term constructed from ancient Greek components. Its core, geront-, derives from the Greek gerōn (genitive gerontos), meaning "old man," which is itself traceable to the Proto-Indo-European root ǵerh₂-, signifying "to grow old." This root is combined with -logia, a suffix denoting a branch of study or discourse, from logos (word, reason). The literal compounding yields "the study of old men/old age." Over time, the term's scope expanded from its literal Greek components to encompass the comprehensive, scientific study of all biological, psychological, and social aspects of aging and the elderly, formalized in the 20th century as the field of gerontology. The suffix -ical then adapts this noun into an adjective, describing anything pertaining to this field of study.
