Final answer:
Spelling errors in MS Word refer to incorrect or misspelled words, while grammatical errors involve mistakes in sentence structure, punctuation, and grammar rules.
Step-by-step explanation:
In MS Word, spelling errors refer to incorrect or misspelled words, while grammatical errors involve mistakes in sentence structure, punctuation, and grammar rules.
Spelling errors: These errors occur when words are misspelled or not recognized by the spell check feature. For example, typing 'teh' instead of 'the' would be a spelling error.
Grammatical errors: These errors involve mistakes in sentence formation, such as incorrect word order, verb tense, subject-verb agreement, or incorrect use of punctuation marks. For example, using 'their' instead of 'there' would be a grammatical error.
It's important to proofread your work carefully and use the spell check and grammar check tools in MS Word to catch and correct these errors.
