Criticism is the practice of judging the merits and faults of something or someone in an intelligible (or articulate) way.

The judder is called "the critic".

To engage in criticism is "to criticize".

One specific item of criticism is called "a criticism".

Criticism can be:

directed toward a person or an animal; at a group, authority or organization; at a specific behavior; or at an object of some kind (an idea, a relationship, a condition, a process, or a thing).

personal (delivered directly from one person to another, in a personal capacity), or impersonal (expressing the view of an organization, and not aimed at anyone personally).

highly specific and detailed, or very abstract and general.

verbal (expressed in language) or non-verbal (expressed symbolically, or expressed through an action or a way of behaving).

explicit (the criticism is clearly stated) or implicit (a criticism is implied by what is being said, but it is not stated openly).
