2 min read

In the past few years, there has been an increase in the popularity of online grammar checker tools such as Grammarly, Hemingway Editor and others paraphrasing tool. There’s no denying that they make it easier for students to produce error-free content. However, being overly reliant on these online tools keep the students from learning much about grammatical errors. If you are one of those students, this blog will inform you about 4 of the most common grammatical mistakes that students make while writing.

Subject-verb agreement:

When you are in college, people expect you to not make this kind of mistakes. And if you are not careful, such a mistake can cause a lot of embarrassment. Remember that the verbs must agree in number with their subjects. In most cases, the errors related to subject-verb agreement happen when the writer uses prepositional phrases. Online grammar correction can help eliminate such errors, but it is better if you identify the origin of this problem.

Incorrect prepositions:

The use of prepositions can often be confusing. You should practice writing shorter sentences to avoid using too many prepositions in a single sentence. Also, remember these following details to avoid such mistakes: • Prepositions in idiomatic expressions remain fixed. • Do not use two prepositions consecutively. • Double-check a dictionary to understand the right use of a preposition.

Also, the more you proofread, the better your knowledge of prepositions get. Using free grammar checks may not be that useful in helping you learn.


You should always consider writing a sentence in the simplest of manner. Avoid adding unnecessary words to your sentences. Wordy sentences not only make the readers get irritated, but they are also one of the major reasons behind erroneous content. You need to streamline your sentences using strong verbs and nouns instead of unnecessary adjectives and adverbs.

Verb tense shifting:

Verbs in the same clause should always use the same tense. Mixing tenses can confuse the readers about the time you are talking about in the sentence. Moreover, while talking about a specific subject, you need to check the tenses in consecutive clauses or even sentences. However, it may make sense to mix tenses at times, especially when you are showing a progression of actions.

There are plenty of other grammatical errors that you need to know about. You should consider proofreading the content manually to learn more about these mistakes.
