We researched and found that common grammar errors do ruin the motive of the speech, and so one should avoid making these mistakes.

Below here is a list of 15 common grammar mistakes that you should stop making to become a professional writer:

1. Sentence Fragments

In simple language, Sentence Fragment is a group of words that drop the essence of the sentence but certainly does not make a sentence. The main subject or a verb is absent from this type of sentence. It is also known as an independent sentence as it has an independent clause. People often confuse it with conjunctions as it also joins words but not sentences.

2. Subject-Verb Agreement Errors (Singular Plural Mismatch)

It is one of the most popular grammar errors and occurs when the verb & the subject does not match; when the subject is “singular,” & the verb is “plural” or vice-versa. It mostly happens when you are not attentive while writing the sentence, or the set of rules is not clear. Subject-Verb Agreement is undoubtedly necessary to gain the perfect moment of your speech.

Just understand that according to grammar, it’s equal to it is or it has and nothing else. People get confused and insert (it’s) as a sign of belonging, but the correct use of is (its). An apostrophe can change the whole meaning of the speech, and so one must remember this petty error, which happens even with the professors of the grammar subject.

Correct: You should not say harsh words to small innocent children.

6. Confusing Pronoun Reference

In a speech, when there is more than one variable with the same pronoun distinct, then it becomes essential to clear up the reference. Neglecting this will confuse and frustrate the readers, and you might end up losing your consistent readers. Avoiding these mistakes will allow you to propose error-free and clear content to your audience.

To avoid this, make sure you know the exact meaning plus spelling of the word you are using in your speech.

9. Unnecessary Use of Commas

11. Heavy Sentences

Too much binding and connecting of phrases makes the sentence really weighty and challenging for the audience to read & understand the meaning or motive of the speech. The first rule of writing something is to make the reader understand it well, and heavy sentences make it super difficult for the reader to understand the message or motive of the speech. One can avoid making this mistake by dividing the sentence into a subpart or just simply making the point in a few words.


Incorrect: Raj is a complex Indian character in the big bang theory, he is bullied and harassed by other characters but at the end he is the love lady of the show and I really enjoy watching it.

Correct: I really enjoy the complex character of the big bang theory show, and watching him get bullied by other people is fun.

12. Comma Splice

The unnecessary use of a comma to join two independent clauses are known as Comma Splice. Instead of using a comma, the rule says to use a semicolon (;) to join the phrase. People make “Comma Splice” when they make use of transition words like however, therefore, moreover, nevertheless, etc.

So do not put hyphen until necessary and also do not forget to put it where necessary.
