A scoped term is a term, the meaning of which is determined by the definition to which it refers in a specific scope/context. Thus, a scoped term has a precise, well defined meaning. One can say that a scoped term is a term that is disambiguated.
The terminology pattern provides an overview of how this concept fits in with related concepts.
A term can have many different meanings, depending on the scope/context within which it is being used. It is useful to be able to distinguish between words/phrases without taking scope/context into account (for which we use the word term), and words/phrases that are part of a specific scope/context (for which we use the phrase scoped term)
