The Reed-Kellogg system - Basic schemata

"Most methods of diagramming in pedagogy are based on the work of Alonzo Reed and Brainerd Kellogg in their book Higher Lessons in English, first published in 1877, though the method has been updated with recent understanding of grammar. ...
Some schoolteachers continue to use the Reed-Kellogg system in teaching grammar, but others have discouraged it in favor of more modern tree diagrams. However, these modern tree structures draw on techniques that were already present in Reed-Kellogg diagrams. Reed and Kellogg defend their system in the preface to their grammar:
The Objections to the Diagram.--The fact that the pictorial diagram groups the parts of a sentence according to their offices and relations, and not in the order of speech, has been spoken of as a fault. It is, on the contrary, a merit, for it teaches the pupil to look through the literary order and discover the logical order. He thus learns what the literary order really is, and sees that this may be varied indefinitely, so long as the logical relations are kept clear.
The assertion that correct diagrams can be made mechanically is not borne out by the facts. It is easier to avoid precision in oral analysis than in written. The diagram drives the pupil to a most searching examination of the sentence, brings him face to face with every difficulty, and compels a decision on every point.
... Reed-Kellogg diagrams abstract away from actual word order in order to focus more intently on how words in sentences function and relate to each other.

"In grammar, clause structure refers to the classification of sentences based on the number and kind of clauses in their syntactic structure. Such division is an element of traditional grammar.
A simple sentence consists of only one clause. A compound sentence consists of two or more independent clauses. A complex sentence has at least one independent clause plus at least one dependent clause.
A sentence consisting of one or more dependent clauses plus two or more independent clauses may be called a complex-compound sentence or compound-complex sentence. ...
A compound sentence is composed of at least two independent clauses. It does not require a dependent clause. The clauses are joined by a coordinating conjunction (with or without a comma), a semicolon that functions as a conjunction, a colon instead of a semicolon between two sentences when the second sentence explains or illustrates the first sentence and no coordinating conjunction is being used to connect the sentences, or a conjunctive adverb preceded by a semicolon. A conjunction can be used to make a compound sentence. Conjunctions are words such as for, and, nor, but, or, yet, so (the first letters of which spell "fanboys"). The use of a comma to separate two independent clauses without the addition of an appropriate conjunction is called a comma splice and is generally considered an error (when used in the English language)."
