In a way that does not show age or is not affected by the passage of time.
She carried herself agelessly, captivating everyone around her.
Agelessly → It is formed from "age" (from Old French *age*, meaning a period of time or life) and the suffix "-less" (meaning without) combined with the adverbial suffix "-ly" (meaning in a manner). The word "agelessly" means in a manner that is without age or timeless.
Think of being 'without age' — 'age' refers to a period of life, and '-less' means without. So, agelessly describes something that exists in a timeless manner.
