Grammar Bytes is the place to go in all those tricky punctuation moments. Full of printable handouts, tips, and rules and advice for every aspect of grammar and punctuation, this website is a great resource. And it’s funny – sample sentences include:
At midnight in Count Dracula’s castle up on the hill, you can hear Diana Ross crooning from the stereo. [Introductory prepositional phrase]
When the computer began to beep wildly, Donald grabbed the monitor and threw it out the window. [Introductory subordinate clause]
That second one is certainly familiar…
But back to the point, great website. Teacher-friendly, but also random-member-of-the-public friendly. Good, clean fun!
