Need free online grammar tool to correct my essay?

Answer 1

There isn't a tool to improve your grammar; you have to be able to do it yourself.

Use a comma when there's a pause in your sentence.

Use inverted commas when you're naming or quoting something you're writing about.

Use a semicolon when putting extra information that links to the first sentence.

Use a colon when you're making a list.

Use brackets or hyphens when you're adding extra, but not necessarily important information into your sentence.
