This is a good list! Thank you, Rkcapps.
English isn't my first language, so during my first two or three years in Australia, whenever I encountered an unfamiliar word, I would look it up in a portable dictionary that I took to school with me. When I write, I still look up words if I'm unsure of their meaning - just to make sure that I'm using the right words.
So most of these examples are familiar to me, but I still came across one or two that I wasn't familiar with (e.g. Historic vs. Historical, Infer vs. Imply).
Speaking of commonly confused words - watching this should be mandatory: "Word Crimes" by Weird Al Yankovic.
In less than four minutes, Al gives us all a funny lesson in grammar, spelling and English generally - and the graphic art and typography is wonderful, and crams in so many tiny jokes too!
