Meaning of terms

In logic, the meaning of terms can be given out connotatively or denotatively. Therefore, to better attain a greater clarity about linguistic meaning, it is necessary to distinguish between intension and extension.

Denotation is stating the meaning of a term by pointing to the thing or individual or by giving examples. For example, in order to, define a school denotatively, one points to GBHS NKOL ETON YAOUNDE. It is like extension of the “collie” consists of lassie, REX and so on.

Connotation is statement of the essential attribute of a term. It gives the deeper meaning of a term. It is like INTENSION which refers to the technical meaning or expert property of a term. For example, man can be connotatively defined as a “rational animal”
