When I statrted to learn English in grade ten in an American high school, there were weekly spelling tests. The teacher would say the word, for ex., "fourth", and then give a contextual sentence: "He was the fourth person sent home."
The spelling lists included common words easily confusable with others, such as "fourth" and "forth" in this case.
I did well on those tests. My teacher was surprised and pleased. What he didn't know was that I still knew so little English I couldn't yet confuse a word I knew (fourth) with one I had no idea existed (forth). Ignorance can be bliss.
