Oldest and eldest– where do they come from?

Although the word oldest and its comparative form older are more common, eldest and elder were used in Old English. They stem from the word eldra, denoting an older person or someone of a higher rank or seniority. As a result of multiple linguistic changes, it evolved into eld and only then old came into existence.

Oldest or eldest – what’s the difference?

Although only a letter distinguishes oldest from eldest, there is a slight difference in their meanings. Both words stem from the adjective old, which has a broad scope as it refers to knowing something or someone for a long time and being of a particular age. It might be also a synonym of the word former. Thus, the superlative oldest covers all that meanings. Eldest, on the other hand, is used especially within a family topic. Moreover, while both oldest and eldest may appear as adjectives and nouns, the latter always appears before a noun, never ends a sentence and cannot be used in constructions using than.
