200 English Grammar Mistakes!: A workbook of Common Grammar and Punctuation Errors with Examples, Exercises and Solutions So You Never Make Them Again

Loose
simply means not bound together. It can also mean not firm
or tightly fitted to something. 
Lose
, meanwhile, means to be without,
deprived of, or stop having.
Incorrect: I am afraid I might 
loose
you.
His pants are 
lose
.
Correct: 
I am afraid I might 
lose
you.
His pants are 
loose. 
Confusion with Their/There
Another mistake common to students lies in this category. It is almost
difficult to identify in speech, but the error is always exposed when
discovered as written statements.
Their
is used as a possessive word. It means belonging to someone or to
them. On the other hand, 
there
is used to mean position, state, etc. 
Example
Incorrect:
The man was killed over 
their
.
These are
 there

Correct: 
The man was killed over 
there
.
These are 
their
books.
Confusion with Your/You’re
The same error happens as for their/there explained earlier. Just like “their,”
your
is used as a possessive word, while 
you’re
is simply derived from 
you
are
(like an abbreviation).

Remember: To know if you are making the right sentences with the words,
ensure you cross-check by replacing the words alternatively. To a large
extent, by alternating the words, you’re good to go. 
Whether you want to use
