Grammar & Punctuation |
||
|
Incorrect Word Order
example
Why I am not living with you?
I am
am I
If this is a question, the word order is probably incorrect. Did you mean “Why am I”… ?
|
||
|
Wrong Use of Tenses & Words
example
He did mentioned this earlier.
mentioned
mention
After the auxiliary verb ‘do’, use the base form of a verb. Did you mean “mention”?
|
||
|

I am done and you?
and
, and
Possible missing comma found.
|
||
|
Wrong Punctuation
example
Teachers are uploading lectures and PPT's to the school website.
PPT's
PPTs
A possessive apostrophe is not correct here. Did you mean “PPTs” (as in ‘more than one PPT’)?
|
||
|
Agreement Errors
example
Thanks for all the reply.
all the reply
all the replies
Did you forget to use the plural form here? If not, consider inserting ‘of’ after the determiner ‘all’.
|
||
|
Incorrect Word Combinations
example
I like the car who has the big wheels.
who
that
Did you mean “that”? ‘Who’ usually refers to a person, whereas ‘that’ refers to an object.
|
||
|
Advanced Missing Commas
example
If it's fine with you go ahead without me
you
you,
Consider inserting a comma after ‘you’ to make the sentence clearer.
|
||
|
Superfluous Commas
example
I did that, because I was told so.
, because
because
If the ‘because’ clause is essential to the meaning, do not use a comma before the clause.
|
||
|
In-Depth Punctuation
example
Mr Peters told me so.
Mr
Mr.
In American English, use a period after an abbreviation.
|
||
| Many more grammar & punctuation corrections | ||
Style |

The word ‘gotta’ is informal.
|
||
|
Unofficial Spellings & Non-Standard Forms
example
The Super Bowl 56 happened in 2022.
Super Bowl 56
Super Bowl LVI
Do you want to use the official name including Roman numerals “Super Bowl LVI”?
|
||
|
Different Measurement Units
example
It was 12 feet long.
12 feet
12 feet (3.66m)
Writing for an international audience? Consider adding the metric equivalent.
|
||
|
Repetition
example
I am able to download the attachment to my local drive. I am able to see the files, but I don't know what to do then.
I am able to see
I can see
You have already used this phrasing in nearby sentences. Consider replacing it to add variety to your writing.
|
||
|
Overused Words & Phrases
example
It will take some time to get to a decision
get to
reach
Replace ‘get’ with a more descriptive word to set your writing apart from others.
|
||
|
Wordiness
example
In order to achieve anything, you should try.
In order to
To
Consider a shorter alternative to avoid wordiness.
|
||
|
Informal Style Detection
example
I will quit my job this month.
quit
resign from
The word ‘quit’ may be considered informal sometimes. Use a more formal alternative in these situations.
|
||
|
Foreign Terms
example
They threatened to resign from their jobs en masse.
en masse
all together
To make your text as clear as possible to all readers, do not use this foreign term. Consider using an alternative term.

Semantics |
||
|
Incorrect Dates

but
-
The word ‘but’ is not needed here and should be removed.

precedent.
Did you mean “precedent”? (As in ‘set an example’)
|
||

nothing
anything
Did you mean “anything”?
|

Format & Typography |
||
|
Inconsistent Use of Numbers & Letters
example
We heard the same story 5 or six times.
5 or six
The numbering is inconsistent as you are switching between digits (1, 2, 3, …) and letters (one, two, three, …). Try to stick to one format if possible.
|
||
|
Incorrect Time and Date Formats
example
I just checked and it's 13:14 am.
13:14 am
If you are trying to use the 12-hour format, the time notation seems to be incorrect here.
|
||
|
Inconsistent Spacing
example
A 30 % increase is sufficient.
30 %
30%
In non-scientific texts, do not use a space in ‘30 %’.
|
||
|
Incorrect Currency Formats
example
I owe him 100 £ for the car.
100 £
£100
The currency mark is usually put at the beginning of the number.

Londonn
London
Possible spelling mistake found.
|

HIPPA
HIPAA
Did you mean ‘HIPAA’, the “Health Insurance Portability and Accountability Act”?
|
||
|
Casing Errors
example
I know the bill of rights.
bill of rights
Bill of Rights
“Bill of Rights” should be capitalized, as it is a proper noun.
|
||
|
ISBN & IBAN Numbers

My IBAN is GB82WEST1234569876543.
GB82WEST1234569876543
