What is the place and role of lexical items in the composition of reasoning

Reasoning cannot be separated from propositions, and lexical items are the basis for the composition of propositions, without which propositions cannot be composed.

In traditional logic, lexical items are the subject and predicate of straightforward propositions. What can serve as the subject and predicate of a proposition is called a concept.

Concepts must be dependent on lexemes for their creation and existence.

The communication of ideas must also take place with the help of vocal or tangible discourse. Phrases are the linguistic form of concepts, and concepts are the intellectual content of the phrases. Different words can represent the same thing and express the same concept.

There is and is only one lexical item that does not appear in the conclusion but only twice in the premises; this lexical item is called the middle item and is often denoted by M.

The main term in the conclusion is called the small term, often denoted by S. The predicate term in the conclusion is called the large term, often denoted by P.

The premise that contains the major term is called the major premise, the premise that contains the minor term is called the minor premise, according to the custom, we usually put the major premise in the front, the minor premise is put in the back, but this is not the criterion for distinguishing between large and small premise. The criterion for distinguishing between large and small premises is their definition.
