In common language, good refers to a thing that is desirable or meritorious; it may also be compared to fair or nice. A good article is one that meets certain criteria:

It is well-written; the content flows logically, and it explains the topic or argument in a clear and engaging way. It has a good title and an intriguing opening paragraph that draws readers in. It is clearly structured, often using headings and subheadings to organize ideas into a clear structure. It is factual and accurate, as well as being free of bias or offensiveness. It addresses its subject with a tone appropriate to the audience, whether serious or lighthearted. It is complete and thorough, covering all relevant angles of the subject. It is readable and understandable to a general audience, although it might be technical or specialized in some cases.

A good article is well-researched, with references and sources where necessary. It has a good introduction, an overview of the topic or argument, and detailed explanations and evidence where possible. It is a well-rounded article, which means that it addresses all aspects of the subject, including opposing viewpoints and the limitations of any studies or claims. It also makes recommendations where appropriate.

In philosophy, the concept of good is a central issue in ethical debates and controversies. It is a key question in the philosophical discussion of morality, as discussed by philosophers such as Immanuel Kant in his Critique of Practical Reason. The concept of the good is also central to theories of well-being, a central tenet of which is that a person’s happiness depends on the things they do and think.

Good can describe nouns as well as verbs, but it is usually used as an adjective: I have a good cup of coffee. The weather is good today. He has a good sense of humor. Good is also an adverb, following linking verbs like taste, smell, look, feel, and appear: It tastes good. The biscuits smell good. You look good in that dress. It feels good to be home.

It can be a synonym for excellent or fine, or used to contrast with bad, ugly, or ugly-looking: He made a really good cake. The view is a good spot for a picnic.

It can be used as an adverb after a linking verb like eat, say, or see: I’m having a good time at the party. It’s a good idea to wear sunscreen.
