Spell check is a feature commonly used in writing software that checks the spelling of words against a dictionary. It flags any words that are not correctly spelled, giving you the opportunity to correct them. Spell check can help identify spelling errors that may otherwise have been overlooked, giving your work a more professional quality. Additionally, spell checks can also be used to help identify misused words, such as “there” and “their,” and non-standard spellings, such as “colo(u)r.” Spell check is an invaluable tool for helping to ensure that your writing is clear and accurate.
