What is a grammar checker?
Grammar checking software scans your writing and then highlights and offers suggestions to correct grammar, style, spelling, and punctuation errors.
Why do we need grammar checker software?
Naturally, grammar, style, and spelling mistakes are inevitable because even the best writer still can slip up.
Often, proofreading your own writing is awkward, and a "second set of eyes" can prove to be extremely helpful.
Good grammar software locates mistakes that you may not normally catch. Rewrite the text with the suggestions offered.
How does the grammar checker know whether my writing is incorrect?
The grammar checking software uses stored parsing algorithms for every word and how the word can be used in good sense to parse your writing.
This information is used to determine word order and phrasing in order to evaluate how it fits with standard grammatical textbook and stylebook rules.
A human editor is still the best.
Humans still beat computers with good writing sense. However, not many of us have access to a professional human copy editor.
Using good grammar and spelling check software is the next best thing to improve your writing. It's somewhat like “having your English teacher looking over your shoulder while you write.”
Next, we'll explain some grammatical qualities of a good grammar checker.
Advantages of a good grammar checker: Structural Clean Writing.
Essentially, grammar is a system of rules that constitute a language and the logic of choice and order of our words.
Proper grammar makes the relation between the words become clear, and we can communicate better without creating confusion.
Knowledge of these grammar rules will help you to communicate better.
Good grammar checking software scans underlying deep sentence structure that results in clean concise writing.
A sentence is made of clauses, and a clause is a group of words that has both a subject and a predicate. Every complete sentence is made up of at least a clause.
The two clause categories are Independent and Dependent Clauses. And basically, seven types of clauses create sentences.
A good clausal checker tool analyzes these seven sentence clause types:
Independent/Main Clause, Subordinate Clause, Coordinate Clause, Relative Clause, Noun Clause, Adjective Clause, and Adverb Clause (includes implied Elliptical Clauses).
Transformational Clausal Structure
A good grammar checker checks underlying Transformational clausal structure and Thematic deep sentence structure correlation.
Try a simple sentence check such as this in any grammar checker: The problems you can encounter in a single sentence is often complex.
A deep sentence scan will indicate the verb error after an implied relative 'that' clause.
Sentence structure is the grammatical arrangement of a sentence and consists of four types: Simple, Compound, Complex, and Compound-Complex.
A good sentence checker tool knows and analyzes sentence structure rules such as (1) a complete sentence must include a subject and a predicate, (2) a compound subject includes two or more subjects, (3) an independent clause consists of a subject and a predicate, etc.
A good sentence checker tool is programmed to know these grammatical rules (and also the many exceptions to these rules).
Which grammar checker is the best? How do the current crop of checkers compare, and how well do they actually work? An honest comparison study can show the structure checking depth of the current crop of checkers:
Take a look at the study. Grammar Checkers: Comparison Tests.
Write Precisely. Try a Phrase Usage Style Check.
1. Choose simple words.
Avoid bookish and overly formal words and phrases.
Write 'use' instead of 'utilize', 'near' instead of 'close proximity', 'help' instead of 'facilitate', 'for' instead of 'in the amount of', 'start' instead of 'commence'.
2. Avoid Wordy Expressions. Don't ramble with wordiness.
Students use three or more words when one word is good enough. Why?
Use specific words for a longer phrase. Do not use more words than necessary to express a thought. Good concise writing uses only the words you need to express an idea. No extra litter. Great writing doesn't need fancy words.
Use 'while' instead of 'during the time that', 'because' instead of 'because of the fact that', 'now' instead of 'at the present time', and 'if' instead of 'in the event that'.
A simple term conveys the same idea and is easier to read and remember.
A good phrase usage style check eliminates these types of writing style errors.
3. Redundancy Reduces Conciseness.
Redundant phrases repeat or express the same thought again.
Some common examples of redundant phrases:
small in size
the reason why
consensus of opinion
in spite of the fact that
A good phrase usage style check eliminates redundant phrases.
4. Write short sentences.
Keep sentences short for the same reason that you keep paragraphs short: they’re easier to read and understand.
Use a Readability Check to determine reading ease. Use a Readability Statistics Analysis to zoom in and tailor each sentence to target your specific audience.
Catch embarrassing punctuation errors
What are the 14 English Punctuation Marks?
The 14 punctuation marks that are used in the English language:
Period, question mark, exclamation point
Comma, colon, and semicolon
Dash and hyphen
Brackets, braces, and parentheses
Apostrophe, quotation marks, and ellipsis
Some common punctuation errors:
1. Missing an apostrophe: Wrong: The mans dog barked.
2. The Comma Splice: Wrong: He was there, she was here.
3. Multiple Punctuation Marks:
Wrong: This is amazing!!!!
4. Incorrect hyphenation:
Wrong: It was pre-eminent.
5. Commas in a series:
Wrong: We have dogs, cats and a hamster.
6. Missing comma with dates:
Wrong: It was April 1 1989 when the accident happened.
A good punctuation check will check for these types of errors.
Catch more errors
A good proofreader identifies more grammatical errors with better accuracy.
Some examples of spell-checking errors in context: Checking homophones in context, checking multiple words and phrases such as "Ne wYork", and contextual word compounding such as "air port, can not, setup, set up, make up, makeup, back up, backup, workout, work out", etc. Many compound words have different verb, noun, and adjective forms.
Some examples of grammar errors in context: Checking for double negatives, double references, dangling modifiers, unclear pronoun reference, verb tense shift, improper parallelism, etc.
Error corrections include explanations that help to improve writing skills.
Most grammar tools claim to be accurate yet rarely catch common contextual spelling and grammar mistakes. Only grammar checking tools that assign Deep-syntactic dependency structures to a sentence can potentially catch in-depth contextual errors.
Use the truly best grammar checker
Overlooked grammatical mistakes can diminish writing quality.
Improve it, and write error-free content.
We wrote our own core grammar engine that uses proprietary research for the correcting of spelling, grammar, punctuation, style, and misused word mistakes.
These rank as the professional standard guides of style, usage, and grammar for writers.
We extensively use "The Elements of Style" as our prominent style reference and recommend it as a manual desk reference. "The Elements of Style" was listed as one of the 100 best and most influential books written in English since 1923 by Time.
Many contemporary authors still recommend it highly. Their praise tends to focus on its characterization of good writing and how to achieve it, grammar being just one element of that purpose.
