Boldfaces are a visual way of emphasizing text in written communication, usually by means of a heavier font. However, there are various synonyms that can also be used to add emphasis to words or phrases. Italicizing text is one way to add emphasis, using a different font with a slanted angle, which can convey a subtle emphasis. Underlining is another way to draw attention to text. Highlighting text with a bright, fluorescent color can also be used for added emphasis, as well as adding an exclamation point at the end of a sentence. Additionally, capitalizing words and phrases is also a way to make them stand out. Overall, using different techniques to add emphasis to text can make written communication more impactful.
