Although the short, simple sentence is the most direct and comprehensible form for an individual sentence, overusing such sentences may make a document seem disjointed. Writing instructors say that a document is better when less important ideas are grammatically subordinated to more important ones so that the grammatical structure emphasizes the logical structure. This document could be improved by combining some of the sentences to subordinate minor ideas to major ones. To do this, join two simple sentences by using a "that" clause or an adverb, such as "although." Put the less important sentence in the subordinate clause after the "that" clause or adverb. For example, the following sentences a. The short, simple sentence is the most comprehensible form for an individual sentence. b. Overusing such sentences may make a document seem disjointed. were combined in the paragraph above. The combined sentence subordinates sentence "a" to sentence "b," thus emphasizing that the information in sentence "b" is more important than that in sentence "a."
