I recommend that all writers find at least three grammar and/or style books they find easy to understand. Each should speak in plain English, meaning their explanations and examples make good, quick sense.

Why not just one? Because, as I’ve found, I need to “hear” an explanation more than once and from different angles for it to sink in. Too, what one book explains well, another doesn’t. (This doesn’t always work, however. I still struggle with who/whom no matter how many books I consult.)

Anyway, here are some of the books on my shelf. Some are no longer in print, but you might be able to get a used copy.
