The simplest way to emphasise something is to tell readers directly that what follows is important by using such words and phrases as especially, particularly, crucially, most importantly, and above all.

Emphasis by repetition of key words can be especially effective in a series, as in the following example:

When a pattern is established through repetition and then broken, the varied part will be emphasised, as in the following example:

Besides disrupting an expectation set up by the context, you can also emphasise part of a sentence by departing from the basic structural patterns of the language. The inversion of the standard subject-verb-object pattern in the first sentence below into an object-subject-verb pattern in the second places emphasis on the out-of-sequence term, fifty dollars.

The beginning and end positions of sentences are more emphatic than the middle section. Likewise, the main clause of a complex sentence receives more emphasis than subordinate clauses. Therefore, you should put words that you wish to emphasise near the beginnings and endings of sentences and should never hide important elements in subordinate clauses. Consider the following example:

In the first version of this sentence, "No one can deny" and "on the business world" are in the most emphasised positions. In addition, the writer has embedded the most important ideas in a subordinate clause: "that the computer has had a great effect." The edited version places the most important ideas in the main clause and in the initial and terminal slots of the sentence, creating a more engaging prose style.
