This document discusses common word choice errors and provides tips to avoid them. It identifies 3 main categories of errors: homonyms, words that differ by one letter, and possessive/contraction confusion. For homonyms, knowing the part of speech helps determine the correct word. For words differing by one letter, creating a memory cue can help, like relating "coarse" to its definition of "harsh." Possessive/contraction errors are most common for your/you're, their/they're, and its/it's, and writing out the full contraction avoids this confusion.
