To learn the correct spelling of words, use a trustworthy and reputable dictionary, either a reference book or an online dictionary. People can use their knowledge about the word to find the correct spelling. It may take several tries to find the right spelling.
For example, a person who wants to know how to spell the word "technique" could use an online dictionary, such as Merriam-Webster.com, to find the spelling. On that website, under the "Dictionary" tab, the person could try typing in several variations until she finds the correct one. Or, if she was using a paper dictionary, she could look under the letter T and start with the first four letters, in this case "tech," to find the spelling.
