Who? Which? That? (The Most Frequently Confused Academic Vocabulary Words, Part 2)

One of the hardest things about learning English grammar is that many of the “rules” are either riddled with exceptions or don’t seem to be very widely known and used. Incorrect usage proliferates the Internet and our conversations so that our ears become accustomed and “trained” to hearing the incorrect form. Even the most well-intending English student can get confused by the hodgepodge of right and wrong. With practice, however, you can familiarize yourself with the correct forms and even develop an ear for them.
