Common Usage Errors: How to choose the correct word

Introduction to Usage Usage deals with how specific words are used in our writing. It sounds simple. However, in the English language there are several words that sound similar and/or are spelled similarly, but have different meanings. There also are several words that are commonly used interchangeably, though they are not necessarily used correctly (for example, “over” and “more than”). Including an incorrect word in our writing can have unintended effects, such as: confusing the reader, changing the text’s meaning, and undermining the credibility of the author. There are pages of words that could fall into this category of incorrect usage. We will only look at 10 of the most common usage errors.
