elderly

the word 'elderly' is a native english formation, built upon the comparative form 'elder'. the root traces back to the proto-germanic aldiz, meaning "grown up, adult, old", which itself derives from the proto-indo-european root h₂el- meaning "to grow, nourish". the suffix '-ly', originating from the old english '-līc', originally meant "body, form" and came to signify "having the character or form of". therefore, 'elderly' literally means "having the qualities of an elder". over time, its meaning shifted from a comparative sense ("more old") to a polite or descriptive term for the advanced stage of age, reflecting a societal categorization based on life stage.

Structure: elder (older) + ly (adjective-forming suffix) elder (from old english ieldra, comparative of eald "old", of germanic origin; functions as the base noun/adjective) + ly (from old english -līc, an adjective-forming suffix meaning "having the qualities of"; of germanic origin)
