Student or Learner
I would like to know if there is any difference between :
The 25-year-old pop singer/The 25 years old pop singer.
I am 24-year-old/ I am 24 years old
are they correct?which is the most common structure?
Thank you in advance
I am 24 years old
I am 24-year-old
I think that "24-year-old" functions as an adjective here (modifier). It must be followed by a noun as it is the case in the 1st example:
The 25-year-old pop singer
A teacher or a native speaker might give you a better explanation.
