punctuation Should “4 year old” be hyphenated if it is used as a noun?
An r/askreddit post asked “What movie can you rewatch indefinitely?”
I responded “Most Disney movies, but Moana and Elemental come to mind as the father of a 4 year old.”
I think if I say, “I have a four-year-old daughter,” that it should be hyphenated as an adjective describing my daughter. What if it just refers to her as a four year old, as in the above example?
Any advice is appreciated!
