Learn English – “24 years old or 24 year old”?

grammaticalityrulesword-choice

I'm wondering if there should be an "s" when telling about ages. I have heard from my native English friend says "I'm 24 year old" is it correct?

Best Answer

When describing someone by their age, you would drop the 's'. This is because when you express a unit of measurement (in this case time, or age) as an adjective, it become singular.

  • The 20-year-old student you're referring to was last seen in the park.
  • I am a 24-year-old college graduate.

However, when someone is stating their age, you would attach an 's'.
This occurs because when a unit of measurement is used as a noun, it becomes plural.

  • He is 32 years old.
  • I am 40 years old.

I think anyway, hope this helps some. :)
