Spell checkers scan documents for misspelled words and suggest replacements. They cannot detect homophonic errors and may not match the user’s intention. Sophisticated applications read words in context and learn from use. Critics argue that spell checkers make people lazier, but others believe they can help with learning a new language and catching mistakes.
Spell checking is a feature available on many computers. Allows users to scan a document for words that have been misspelled. Most word processing programs have a built-in spell check function, and you can find spell checkers that can be integrated into instant messengers, web browsers, and other types of programs. Having a spell checker isn’t exactly a substitute for a real human editor, but it can help people catch basic spelling mistakes so their communications are more presentable.
Early spell-checking programs simply scanned documents for words they didn’t recognize and warned users that something was misspelled, without making any suggestions for alternative spellings. These systems were eventually replaced by spell checkers which generated a list of possible words from which the user could select to replace the misspelled word. For example, if a user typed “thru,” the spell checker might suggest “threw” or “through” as possible alternatives. These programs also allow users to add exceptions to the program dictionary.
One of the main problems with a spell checker is that it cannot detect homophonic errors and users can even generate homophonic errors accidentally if they are not familiar with the language. In the example above, the user may have typed “I went through the door” and selected “thrown” instead of “through,” without realizing they made a mistake. Especially for people who really struggle with spelling, the computer’s suggestion list may not match the user’s intention at all. For example, if a user types “She was very busy checking my work,” the computer is unlikely to suggest “complete,” the correct word, as a replacement for the incorrect word.
Some people have attempted to remedy the homophone problem by developing more sophisticated spell checker applications that read words in context instead of just looking for words that are not spelled correctly. These programs can detect some homophone errors and will also avoid suggesting multiple homophones for a spelling error, making it more likely that the user will select the word he intends to use. These programs learn from use, which means that each generation will be better than the last.
Some people have criticized the widespread use of spell checking utilities, arguing that they make people lazier, as people assume that spelling errors can be corrected, rather than learning to spell words correctly or learning to identify homophonic errors . These people theorize that the state of written communications has been undermined by the use of spell checking programs. However, others have argued that using a spell checker can make people feel more comfortable while they are learning a new language, and that everyone can make typing and spelling mistakes that they might not easily identify without some help. , since it is often difficult to catch mistakes in one’s work.
