Importance of Grammar and English Grammar Check to Correct Errors English developed over the centuries, drawing from different languages and cultures and as such there are ambiguities. Use of the incorrect word, tense of a verb, punctuation or joining together two phrases incorrectly can give rise to misunderstanding. This is why everyone must have a fairly reasonable grasp of grammar. However, it is the very complexity of rules, sometimes conflicting and sometimes contextual, that can be difficult to remember and apply.
It is very common to come across errors such as using “than” when the writer meant “then” or contractions such as “its” in place of “It’s” or “you’re” instead of “your”. “Effect” is often used in place of “affect”, especially in American English. Each sentence must be precise and clear as to what the writer wishes to convey and this is the reason it is important for writers or even speakers to have a command over grammar, not just vocabulary. One of the quirks of English language or any other language, for that matter, is that you cannot learn rules of grammar alone. It goes hand in hand with sentence construction and elements of composition.
