Elder vs. Older
Cambridge distinguishes the wider comparative “older” from the more restricted “elder.” “Elder” is normally attributive and especially common for family relationships, while “older” can describe people or things and can also appear after a linking verb.
Use “older” broadly for age comparisons. “Elder” can mean older too, but as an adjective it normally comes before a noun and is especially associated with family relationships.
Key details
Choose the right form
| Meaning / situation | Form / construction | Decision |
|---|---|---|
| a family relationship is named before a noun | elder + family noun | Use “elder” attributively in the documented family use. |
| a general age comparison is being made | older | Use “older” for people broadly and for things. |
| the adjective follows a linking verb or appears in an explicit than-comparison | older | Prefer the unrestricted comparative rather than forcing “elder” into a position the reviewed grammar restricts. |
Quick tests
Meaning / construction test
Are you naming an older family member directly before the relationship noun?
If yes: “Elder” is available in that restricted family pattern; “older” also remains possible.
If no: Use “older” for general comparisons, for things, and in positions such as “is older” or “older than.”
Caveat: The distinction is not simply formal versus informal. The reviewed Cambridge grammar gives “older” the broader distribution and restricts attributive “elder” especially to family relationships.
Examples
Maya is my elder sister.
“Elder” appears before a family-relation noun.
My sister is older than I am.
The explicit comparison uses the broader comparative “older.”
This bridge is older than the station.
“Older” applies to things as well as people.
Further guidance
Core difference
“Older” is the general age-comparison form; “elder” has a narrower attributive, often family-related use.
Fast Test
Use “older” if the comparison concerns a thing, follows a linking verb, or simply needs the ordinary comparative. Use “elder” before a family noun when that conventional wording fits.
Usage Boundary
Do not write “She is elder than him” in ordinary modern English; Cambridge treats predicative comparison as a job for “older.”
