What is it that makes a word tricky? Is it the fact that it’s funny and hard to pronounce, like discombobulate? Or is it the fact that it has many meanings, like the verb to set? Irregular verbs are, by their nature, tricky little words and they have to be learned by heart. Compound words can be tricky as well. For an English language learner, a person who’s yet to discover all the rules and rhythms of the language, some of the trickiest words to learn are tricky simply because they are confusing.
