Grammar is a science dealing with the formulation of the proper methods of
verbal expression and communication, i.e., the methods of organizing words
(concepts) into sentences. Grammar pertains to the actions of consciousness,
and involves a number of special concepts—such as conjunctions, which are
concepts denoting relationships among thoughts (“and,” “but,” “or,” etc.).
These concepts are formed by retaining the distinguishing characteristics of
the relationship and omitting the particular thoughts involved.
