Consider the use of transitions, for example. Transitions are like signs for your readers. They give direction and they help to link things together. Good transitions move the reader from one point to the next, and they also focus the attention of the reader on the main idea of the essay. You can use words or phrases as transitions, but you must be careful to choose words that indicate the right relationship between ideas. Here are a few examples of relationships you can indicate with transitions:

Show addition: and, also, in addition, furthermore.

Give examples: for example, for instance, specifically

Compare: also, likewise, similarly

Contrast: however, on the other hand, yet, although

Summarize or conclude: therefore, in other words

Show time: after, before, during, next, finally, meanwhile, immediately

Show place or direction: above, below, nearby, close, far, left, right

Indicate logical relationships: therefore, consequently, as a result, thus, since, because.
