Ever since word processing programs became popular, grammar correction programs have been one of the most useful tools used by English language writers all over the world.
A grammar correction program can make writing an English composition easier and quicker by helping the writer detect any grammatical or spelling mistakes in their composition.
With the use of a grammar correction program, a writer can expect to write compositions more confidently, faster and more accurately.
The great thing about grammar correction programs is that it helps anyone write properly grammatical compositions, even those who are not very good at English composition or even those who do not naturally speak and write English.
A grammar correction program is usually included along with a word processing program as it is usually designed to check for grammatical and spelling correctness as the user is typing or composing his or her documentation.
This "real time" error checking and correction of grammar correction programs make them invaluable tools for writers who want to make sure that every word and sentence that they type on their computers do not have mistakes.
Some writers, however do not like to be disturbed by mistake-prompts as they work.
They want to go with the flow of their writing and deal with the mistakes only after the writing is completely done.
Grammar correction programs can be used in these cases as well.
Grammar correction programs can usually be set to check for mistakes only until the user prompts it to do so.
Once the user prompts the program to begin checking the composition, it quickly scans through the document that the user made and marks mistakes that it comes across.
Aside from detecting mistakes, grammar correction programs can also introduce the proper corrections to any mistakes that it finds.
Thus, if the user types "dcoumnet" instead of "document", the program will detect the wrongly spelled word and either suggest the proper spelling of the word or prompt the user for several possible correct spellings of the word.
There are also two ways that grammar correction programs can handle the mistakes that it detects.
It can either automatically correct them or it can prompt the user and ask for what corrections to use.
Usually, it is best that the user reviews each change that the grammar correction program wants to make.
This is because grammar correction programs do not actually "understand" what you are writing in the sense that humans understand.
It can only detect the words that you typed and the structure that you typed them in without taking in what it really means.
Therefore, there is some possibility that the changes that the program wants to implement may not mean what you want the sentence to mean, though the sentence is essentially grammatically correct.
