1. To be or not to be
To be is the first auxiliary verb both native speakers and ESL students learn about. When to use am, are, is, was, and were has been drilled into our brain since primary school, yet it is quite common English mistakes made by native speakers that it’s infuriating. Using expressions like “We was” or “I is” or, God forbid, “Is our children learning?” is the quickest way to be perceived as illiterate in almost any company.
