Diagnosis has two primary definitions:
- Many people associate the word with established medial practices. Merriam Webster defines diagnosis as the art or act of identifying a disease from its signs and symptoms.
- Another widely used definition stipulates that the word can be used in a more general sense. Diagnosis can be used to describe any investigation or analysis of the cause or nature of a condition, situation, or problem.
In both cases, diagnosis is a noun. In the first definition, it is used in a medical context. The second definition could be used to describe the analysis of any condition, situation, or problem.
In very basic terms, a diagnosis is the result of a skilled individual identifying a problem based on tests and observations.
