Age vs. Ages vs. Aged: Expressing Children's Ages Correctly
When describing how old children are, especially when using these descriptions as adjectives before a noun, writers frequently stumble over whether to use age, ages, or aged. Getting this right ensures your writing remains professional, grammatically sound, and easy to read.
Core Rule Definition
How you express a child's age depends entirely on its grammatical function in the sentence:
- Aged (or Age): When placed before a noun as a compound adjective, the standard phrasing uses hyphens and singular units. For example, "a five-year-old child." Alternatively, British and formal English often use "aged" ("a child aged five").
- Ages: Used as a plural noun (e.g., "The ages of the children vary") or informally to mean a long time (e.g., "It took ages"). Never use an 's' on the unit of time inside a hyphenated modifier (e.g., never say "a five-years-old child").
- Age: Used as a singular noun (e.g., "at the age of five") or in loose adjectival phrases without hyphens (e.g., "children of school age").

Before & After Examples
Example 1: The Hyphenated Compound Adjective
- Incorrect: We are looking for a nanny for our five-years-old twins.
- Correct: We are looking for a nanny for our five-year-old twins.
- Explanation: When a phrase modifies a noun directly from the front, the internal nouns (year) must remain singular, and hyphens link the words together.
Example 2: Post-Nouns and Prepositions
- Incorrect: The camp is designed for children age five to ten.
- Correct: The camp is designed for children aged five to ten (or between the ages of five and ten).
- Explanation: When describing the age after the noun or describing a range, use aged or the formal noun phrase ages.

Mnemonic Memory Device
"Hyphens hate plurals!"
Whenever you squeeze descriptive words together with hyphens before a noun (like five-year-old), force every internal unit of time (year, month, week) to stay strictly singular. No "s" allowed inside the hyphens!
