a comments in this post says

I see no "dot product", which usually refers to vectors. This is a matrix product

which means the term "dot product" is only used for vectors, and the term "matrix product" is only used for matrices.

similarly, square foot (or square meter) is only used to describe an area rather than a distance, strength, or any other topic.

Is there a term/word/phrase to express "only used in a specific topic"?

  • Could you give an example of a sentence in which you'd use the word? Vectors and matrices aren't what are commonly understood as fields. Regardless, the word restricted and its synonyms are likely apposite to this matter. – userr2684291 Aug 25 at 15:05
  • @userr2684291 Vectors and matrices aren't what are commonly understood as fields, are they commonly understood as topic? – Jay Aug 26 at 0:37
  • Neither. Vectors are mathematical constructs, objects, and matrices are a way to represent them (among other things). – userr2684291 Aug 26 at 16:47

The term you are looking for is Specifically defined

This term can be found used in numerous articles on the internet.

My vote for the canonical name is ATA Boy.

  • Thanks for your answer! So, the whole piece could be "dot product" is specifically defined for vectors, whilst the term "matrix product" is specifically defined for matrices, right? – Jay Aug 26 at 0:30
