Who needs charming prince?
I found that sentence.
I would have written “ who needs of a charming prince?”
Someone could explain me why this sentence is written without “of a”

Exemple: who needs of a dog? Isn’t the same?

Thanks!

Answer

Hello - the ‘of’ doesn’t serve any function here. You have the question ‘who needs’ and the object of the question ‘a charming prince’. ‘Of’ has no place in the sentence, but the article ‘a’ is necessary, to indicate the noun ‘Prince’.

Answer

I think you mean "who HAS need of"
