Somewhere between third-grade and writing SOAP notes at 5am I lost some of the grammar basics. If you also find yourself struggling with the basics from time to time, this is a great flowchart for figuring out where and when to use apostrophes, an oft miss-used punctuation mark.
For some of us, grade-school grammar lessons haven’t stuck. I managed fairly well with my trusty Elements of Style until pretty recently, but the ongoing assault on grammar that is the Internet occasionally shakes my confidence. (Every time I want to type rein, rain, or reign, for example, I need to close my eyes and meditate for a moment.)
