Who is Eldest?
Eldest most commonly refers to a person born at the earliest or most significant age among a group of people.
Eldest is usually used when the people in consideration are related, maybe a family or a small community.
It is an attribute to denote the seniority of someone and is, therefore, an adjective. It is used to indicate the person whose age is the highest. Hence, it is a superlative adjective.

- She’s her eldest sister.
- Ram is the eldest of all the cousins.
- The king’s eldest son would succeed to the throne after the king’s death.
Who is Oldest?
Oldest refers to someone more senior than any other person or thing in that category. It can be used to compare people, things, or ages (like the stone age is the most senior age in the periodization of history) and whether they are related.
Eldest can’t be used for absolutes; only oldest can be used in case of absolutes of the world. For example, “She is the oldest lady alive”.

Main Differences Between Eldest and Oldest
- Eldest is used to denote seniority among related people. In contrast, Oldest indicates seniority and antiquity among people or things (like kingdoms, infrastructure, monuments, etc.) that may be related or unrelated. Oldest is usually used to determine whether the considered objects were contemporary or ancient to align the ages of various entities.
- Eldest is constructed from the root word ‘Elder’, a comparative adjective, while Oldest is derived from ‘Old’, a Positive Adjective.
- Both are used before nouns to describe their age attribute, but Eldest is used for only selective nouns that represent people, while Oldest can be used for all the nouns (whether it be people or thing)
- Eldest is used for related groups (like families or companies) of people only, while Oldest is used for related or unrelated groups of people or things. Only the Oldest is used to denote absolute superlatives of an entire country or a world.
