Top 10 English Grammar Mistakes and How to Avoid Them

We all make mistakes using grammar, and there are many that people make over and over again. You’ve probably seen it for yourself; someone will use “it’s” instead of “its” or “you’re” instead of “your.”. Here are some of the most common grammatical mistakes and how to avoid them so you don’t fall into the trap.


One of the biggest mistakes people make is: not knowing when to use “who,” “that” or “which,” in a sentence. “Which” is used for things (including animals), Who or whom (antiquated) refers to a person, and “that” refers can be used in reference to animals or things. People are always mixing these up.

Another batch of words that get mixed up are: “they’re,” “their,” and “there.” People will often misspell “their,” and use them interchangeably. This is a huge grammatical error because “they’re” is a contraction for “they are,” and “their” is possessive. “There” is used to refer to a place, but people often use it in place of the other two.

Two more other words that are commonly mixed up are: “its,” and “it’s.” The former is possessive, so it refers to something that belongs to a person. The latter is a contraction, so it is used in place of “it is,” and is not in a possessive form.

People will also confuse “any one” with “anyone.” The former refers to one person, and the latter is used in conjunction with many people. If people took the time to understand what these words mean, they wouldn’t get them mixed up.

A lot of words get misspelled over and over again by many people, and a few of them are: “alright,” “responsible,”, “successfully,” “separate,” “recommend,” “dependent,”, “commission” and more. These misspellings happen so often that the misspelt word is more often seen than the correct one.
