Nowadays, we use the word paradigm with a very specialized meaning – to denote a given school of thought, way of thinking, or tendency. A bit more formal definition could be - "Logical or conceptual structure or pattern, which serves as a form, example of thought within a given sphere of experience or scientific field." Once again, we could see how a word could develop quite subtle and distinct connotations. But where does paradigm come from and how come it was given such a specified meaning?
