What is critique?

From the 'eipcp' website I found the article 'What is Critique?'

And it made me think about how cruicial critique is in the art world. The art world would not exist without critique. It can be defined as meaningful differentiation of concepts or a “practice that suspends judgment”. The term ‘critique’ was first called “technique” and “art”, which is found through centuries in many Europenan languages. This is interesting because the term critique was originally related to art, so therefore a term which must stay in relation to art. Art would not be art without a critique.
