It doesn’t matter if you are a student, business professional, or an engineer. No matter who you are, communications skills matter. One of the most important of these skills is the ability to use words correctly. This is why every iPhone user should have at least one dictionary app ready to access when they are unsure of the meaning of a word, when they wish to determine if they are using a word in the correct context, or when they wish to find a substitute for a word.
