Which of the following tools would help improve written accuracy regarding spelling?

Using spell checkers is an effective way to improve written accuracy regarding spelling. They automatically scan your text for misspelled words and suggest corrections, which can help catch errors that a writer might overlook when proofing their work manually. Spell checkers utilize extensive dictionaries and algorithms that can identify not only simple typographical mistakes but also provide suggestions for homophones and common grammatical issues. This tool serves as an immediate reference, allowing writers to enhance the clarity and professionalism of their writing by ensuring that words are spelled correctly before finalizing their documents.

While pen and paper can aid in the writing process, and methods like online forums and peer reviews can help improve writing through feedback and discussion, they do not specifically target spelling accuracy to the extent that spell checkers do.
