Origin of eldest

Explanation
Someone who's described as eldest in their family was born first. Your eldest sister is the oldest one. Use the adjective eldest when you're describing people in terms of birth order: the oldest is the eldest. Your eldest friend is older than your other friends. You can also use the word as a noun, meaning "firstborn." Your mom might introduce you by saying, "This is my eldest." It's a somewhat formal, old fashioned word, much less popular today than "oldest."
