A dictionary is beneficial because it can help a person learn more about a particular word such as what the meaning of the word is, if the word should be capitalized, what the syllables of the word are, how to pronounce the word, the history of the word and can also help non-native speakers understand foreign words or phrases. Dictionaries also offer a sentence or an expression that uses the word so that the reader can get a better sense of how the word might be viewed in context.
For any person that is learning a new language, writing a paper, reading a book or newspaper or holds a job that requires communication, the dictionary is an indispensable tool. There are electronic dictionaries that are available and can be brought from place to place. These dictionaries are perfect for students who are learning a foreign language and want to be able to translate words between languages while out of the home.
The more standard dictionary comes in a book format and is a great choice for people who can utilize the dictionary at home. There are also online dictionaries that are great for pronunciation because they will pronounce the words out loud. Using a dictionary, regardless of the type is also a great way to ensure that the spelling of the word or words is correct.
