The Weekly Countdown – 52 Common Errors for ESL Learners


Do you know that probably everyone has failed at something?  Even very successful people?

Steve Jobs in his 2005 graduate address at Stanford emphasized the importance of failure to success, when he explained that he was fired at the age of 30 from the company he co-founded.

“It turned out that getting fired from Apple was the best thing that could have ever happened to me,” he said. “It freed me to enter one of the most creative periods in my life.”

So can this theory of “making mistakes” be applied to learning? And especially in learning a second language?  Many educational theorists and educators believe so. They state there is great value in mistakes in learning. Mistakes inspire you to learn. Well, with that said, this article focuses on just that… 52 common mistakes for the ESL speaker

1.     Some nouns borrowed from other languages keep their original plural forms: datum, data; cherub, cherubim; crisis, crises.

2.     Other foreign words use an Anglicized plural or the foreign plural: appendix, appendixes/appendices; curriculum, curriculums/curricula; formula, formulas/formulae

3.     Some nouns occur in the singular form only: much dust, not much dusts; more courage, not more courages; less fun, not less funs. These nouns are called mass nouns or non-countable nouns.

4.     There are over a hundred finite verbs that form the past tense and past participle without adding “ed”. These verbs are often groups of words that include such auxiliary verbs as can, must, have, and be.  These past tense and past participle verbs are irregular in form and are best learned through use:

However, as more and more women move into these roles and to avoid sexist language, you can use both third person singular pronouns: A mayor must use his/her discretion in how to solve the dispute. Or you can use a plural form: Mayors must use their discretion in how to solve the disputes.

11.     Omitting determiners or articles so the sentence is ambiguous: When my mother showed up at the furniture store, she was accompanied by a friend and interior decorator.

For example: My brother wants a white new car to drive. This sentence is incorrect as the color of the car comes before the age of the car. The sentence should read: My brother wants a new white car to drive.

45.     The subject of a sentence should not be repeated in pronoun form. Example: My engineering professor she is very smart. You should say: My engineering professor is very smart.

46.     Over-reliance on traditional phrases. Often, two logically-related sentences do not need a transitional word to link them. For example, “The beaver gnawed on the tree. Consequently, it fell down.” In this instance, “consequently” is not needed because readers can figure out for themselves that the tree fell as a consequence of the beaver’s chopping.

47.     Use of continual and continuous:  Continual means something that’s always occurring with lapses of time. The continual music next door made it hard to study for finals. Continuous means something continues without any stops or gaps in between. The exercise teacher’s continuous talking took away from the workout session.

48.     Use of farther and further: Farther implies a distance that can be measured. Further is used for lengths that are more abstract. For example: The driving distance from my house to my college is farther than the driving distance from my friend’s house to her college. The stock market crash caused further worry to all of the investors.

49.     Use of since and because: Since refers to time. Because refers to causation. Example: Since I finished my resume, I will ask my friend to edit it. Because I finished my resume, I will now be able to ask my friend to edit it.

50.     Use of anxious and eager/excited: Anxious implies a fear or anxiety. Eager/excited means you are looking forward to something. Example: I was anxious when I had to give the sales presentation. I was eager/excited to give the sales presentation.

51.     Use of irony and coincidence: Irony is the incongruity in a series of events between the expected results and the actual results. Coincidence is a series of events that appeared planned but are actually accidental. So it is ironic that a team that has no wins in basketball would win first place, especially when half of their team members were sick. It is a coincidence that you go to Disney Land and you see your neighbors there also when you never knew they were going in the first place.

52.     Use of impactful or impact. Impactful is not a word and although you might hear it, it is not standard English. Use impact instead. The impact of the online English classes helped me secure an overseas sales job.

So go ahead and make mistakes. The important thing is that you see mistakes as a means to improve and reach success. Steve Jobs knew all about that. Write and tell me what you think about this article. About mistakes. About language learning. We’re here to help you become successful.
