The briefest English grammar ever, Colman R., 2005.
When English speakers begin to learn other languages they often find themselves being taught via methods that assume they have a basic knowledge of English grammar.
I hope this little book will fill a gap and give you the basics, whether you want to learn another language or not, and if you do, whether your aimed-for second language is Spanish, Anindilyakwa, New Testament Greek, Swahili or anything else.
