Logical Sentence Construction Logical sentence construction relates ideas and details clearly and in an orderly pattern. Mixed sentences contain parts that do not fit together in grammar or in meaning. Care must be taken when using compound construction and comparisons to maintain clarity. Subordination and Coordination Well-structured sentences use coordination, subordination and parallelism to relate ideas and details clearly. The beginning and the ending of a sentence are its most emphatic positions.
Coordination is used for ideas that are equally important.
Subordination is used for ideas of lesser importance. A clause is a group of related words containing a subject and a predicate. It can be either independent or dependent. Adjective clauses modify nouns, pronouns or groups of words used as nouns. They are introduced by relative pronouns or subordinating conjunctions.
