A new writing tutorial web site launched today, with its first offerings tackling that old stumbling block, the apostrophe. Using examples from public signs, advertising, and newspapers, The Writing Kit's Apostrophe Tutorial presents learners with clear animated explanations of how to use the apostrophe and, equally important, with plenty of interactive opportunities to practice using it correctly. The Apostrophe Review module builds on that approach, allowing learners to consolidate their knowledge.
