You can often improve coherence by providing transitional words or phrases to clarify how ideas relate to one another. Many of these transitional devices are simply the conjunctions used to join clauses together in order to create compound or complex sentences. Others are add-ons that direct readers’ attention to the relationship between ideas.
Transitions are powerful aids to understanding because they help readers identify the relationships between ideas. They are so powerful that readers may rely on them to connect ideas even where no such connection exists. Read the following paragraph:
As you read the passage for the first time, did you, at least momentarily, seek logical connections because of the transitions? When we read the items in a list without the conjunctions, the lack of relationship between the ideas is immediately evident:
If transitions can create even a fleeting appearance of connection among this strange collection of sentences, imagine how useful they can be in clarifying connections among logically related points.
Sometimes simply adding for example or in other words at the beginning of a sentence will improve the flow of ideas. Without such signposts, readers may assume that what they are reading is a new point, become confused, and need to reread a passage to make sense of it. Every time readers stop and go back, they lose some of the information held in short-term memory and thus have more difficulty comprehending and remembering what they are reading.
The following table provides a partial list of transitions, indicating some of their more common uses. Use these transitional words and phrases wherever you feel the reader will benefit from a signpost indicating how ideas relate. Note, however, that any stylistic device you can use too little of, you can also use too frequently. Sometimes the connections between ideas are clear from the context. Not every sentence needs a transition. But transitions are particularly important when writing for an audience composed of non-specialists so that they can follow the logic and organization of new and sometimes difficult information.
The following two tables list the prepositions and conjunctions most commonly used, respectively, to signal how ideas are related.
