What is the difference between 欲しい and 要る?


I have a question regarding the difference between 欲しい and 要る.

So far, what I know both words mean "want". The first one is an adjective and
the second one is a godan verb with -ru ending. Now, I confused about the
sentence below.

> こんなレプリカは いらない

does it has the similar meaning with?

> こんなレプリカが欲しくない (I make this sentence by myself)

what is the difference in those sentence? Thank you.




The word 要る can be translated as "to want," but it's more about necessity. If
you look at a Japanese dictionary, you are likely to see a definition as
simple as 必要である.

欲しい is about desire, 要る has to do with necessity. Though, obviously sometimes
the two concepts have some overlap.
