Does「がる」conjugate?


It's an auxiliary verb, so I'm not sure whether or not it can conjugate. For
example, is it correct to end a sentence with「。。。が欲しがります」？ Also, if you, for
example, wanted to say that someone wants to want something,
would「[誰か]は[何か]が欲しがりたいです」work?




Yes, it can conjugate just like a normal godan verb.

  * 欲しがらない
  * 欲しがります (-ません, -ました, ...)
  * 欲しがれば
  * 欲しがれ
  * 欲しがろう  
(This is rare as the "let's want" sense, but can be used as part of the
[(よ)うと/(よ)うが construction](https://jlptsensei.com/learn-japanese-
grammar/%E3%82%88%E3%81%86%E3%81%A8%EF%BD%9E%E3%81%BE%E3%81%84%E3%81%A8-%E3%82%88%E3%81%86%E3%81%8C%EF%BD%9E%E3%81%BE%E3%81%84%E3%81%8C-you-
to-mai-you-ga-mai/), e.g., 欲しがろうが欲しがるまいが与えられる "is given regardless of whether
one wants it or not")

But it has many semantic restrictions, so please read
[this](https://japanese.stackexchange.com/a/23861/5010) before using them.

When do you ever say "I want to want it" in English in the first place? 欲しがりたい
may be usable in a very limited context where the way you show your desire to
someone is important, but it's probably best to forget something tricky like
this until you reach the near-native level.
