The common mistake in English grammar made by the common peoples:
There are three types of errors 
in English grammar.

Mistake in English grammar

1. Grammar, 
2. Usage, 
3. Pronunciation.

1. Grammar 

refers to the fundamental principles and structure
of the language, including clear and correct sentence construction
and the proper forms of words. This category includes
mixing up transitive and intransitive verbs (such as “lie” vs.
“lay”), mixing up the correct forms of pronouns (such as “who”
vs. “whom”), and using a verb that doesn't agree with its subject
(as in “Everyone are going to the store”).

2. Usage 

refers to the way that particular words are used.
Such errors include mixing up words that sound alike (such as
“affect” vs. “effect”), mixing up words whose meanings are
related (such as “imply” vs. “infer”), using made-up words (such
as “irregardless”), and using so-called clutter expressions that
don’t add anything to your meaning (such as “at that point in
time”).

3. Pronunciation 

                         problems are important because mispronouncing
a word will definitely affect the way people perceive
you. In Chapter 13, you’ll see the correct pronunciations of
some of the most frequently mispronounced words in English,
such as “nuclear.”
