What tool checks the spelling of each word against the program's internal dictionary?

A. Spell checker

B. Thesaurus

C. Formatting toolbar

D. Find and Replace

The correct answer is option A.

Explanation:

A spell checker is a tool that we as Internet users can use to confirm that what we are writing is correct and has no spelling errors.

It works by looking for the word you have written and comparing it with thousands of words that it has stored in its database, which works like a dictionary, to be able to determine if the way in which you have written it is correct.

Remember that a spell checker only corrects words spellingly and not grammatically, so that I could write "the plain is flying" and it would be acceptable since the word plain is an accepted word.
