How to use the Grammar Check

The Grammar Check works similarly to the spelling and grammar checkers in a word processor. It highlights any word that’s not in our dictionary in case it’s misspelled. It also looks at the construction of the sentence to make sure that the structure, punctuation and tense are correct.

But, in addition to these standard grammar checks, our team of copyeditors have been inputting thousands of specific checks that they have come across in their years of editing. Our goal over the next couple of years is to have a simple explanation associated with every grammar issue that the software picks up.

Example 1: “Adverse” vs. “averse”

One of our editors noticed that writers often mistake “adverse” with “averse”. One is an adjective, the other is a verb. They created a programming rule around this issue. So if you have a sentence construction that uses “adverse” as a verb, the grammar checker will highlight it and offer the following explanation:


You may mean averse in this instance.

Adverse and averse are both used to convey a negative idea, but adverse is an adjective meaning something that's harmful, e.g. adverse weather conditions, and averse is a verb meaning 'a strong dislike', e.g. She is averse to the idea of marriage on philosophical grounds.


Example 2: “Allows” followed by a gerund

Another of our editors noted that the word “allows” should never be followed by a gerund. A gerund is a verb that has been turned into a noun by adding -ing. “Walking on the beach is my favorite pastime” or “John was afraid of skydiving”.

So, any time the software finds this construction, it highlights it and offers this explanation:


Allows + gerund, e.g. "allows identifying", is incorrect.

You need use the infinitive (base) form of the verb instead of the gerund (-ing) form of the verb. You also need to include an object, giving the structure allow + object + infinitive, e.g. "allows it to be identified".

Alternatively, you could use the noun form of the verb with the structure allows + noun + preposition, e.g. "allows identification of", followed by the object.


Our editors have created thousands of these checks and the list continues to grow each week.

We hope that our explanations will build the knowledge of our users and help them become better writers!

The Constitution of the Federal Democratic Republic of Ethiopia provides each of the regional states with the legislative power to draft, adopt and amend their own constitution fitting to its own local circumstances. Thus, Benishangul Gumuz Regional State (hereafter used as BGRS) drafted and adopted its own constitution. The 2002-revised constitution of the region vividly recognized the establishment of administration of nationalities as administrative hierarchy by replacing the former Zonal Administration. Therefore,the writer of this paper collected various empirical evidences and appropriate legal documents to explain the paradox of incompatibility of legal principles and actual practices concerning nationality administration in BGRS.The regional state does not follow its own constitutional provisions concerning administration of nationalities practically. Hence,the writer contends that constitutionally, nationality administrations in BGRS have important powers but practically these powers are symbolic or nominal.

I'm disappointed as your tool is unable to detect grammar errors such as misplaced or no articles, commas, etc. Why? It needs to be incorporated in the tool to expedite editing.

I've noticed that my summary report is showing grammar errors while the grammar tab reveals nothing. The problem seems to be incorrect application of em dashes (eg spaces either side). It would be useful if the grammar option would highlight these.

I checked a 77,000 word document with the Grammar checker tab and it reported back "no issues." That is not possible.. Do you have an accurate version hidden away I can access?

By chwood01 on 11 December 2018, 01:49 PM

Useful, but I wish it would give us the option to not check names and such... my spelling report is always low because it doesn't recognize the characters' names I use in my writing... Then there's the problem of sentences in foreign language in dialogues, but I guess nothing can be done about that. Maybe a way to uncheck those words, so as to get a more accurate result?

By cathy.magden on 29 December 2018, 02:10 PM

How come I can't correct the end quotes to dialogue? I get a lot of errors and when I go to correct, it never corrects. Even if I go into work and check them there. How do you eliminate those errora?

By saturnn77 on 08 January 2019, 05:50 PM

I need a text editor that shows the error and explains why it is an error.

By whaziz on 29 January 2019, 04:20 PM

I am satisfy with other facilities but the grammar check. It is very weak even compared to free version of Grammarly. In academic writing, we often use past perfect tense when writing rebuttal letter to the reviewers. And simply the grammar check missed to correct the verb to verb 3 mode. Can you check on this: "we have wrote a letter", it should be "we have written a letter"

Why don't you accept some foreign words, like fifteen in Greek to be added to my dictionary, which is already full of words in Latin, Greek, Spanish, Italian and German? This is not the only case, there are several, and its annoying to have it pointed out that you have errors in your spelling.

By brfkol4 on 02 February 2019, 12:55 PM

Hi there, we are working on adding more support for other languages in the future. For now, you can always click "add to dictionary" to stop seeing those suggestions. Hope that helps!

By kylemassa on 04 February 2019, 06:11 PM

Can we permanently disable grammar rules? I'm thinking of spacing for the en dash or whatever it's called.

By flight44 on 23 February 2019, 06:56 PM

Hi there, apologies but there's no way to permanently disable a rule at this time. You can always click "Ignore" to remove the suggestion while you're editing. Hope that helps!
