 It was found that the use of a dictionary can help learners of a foreign language write better if they know how to use them.Foreign language learners can make use of grammar-related information from the dictionary to select appropriate words, check the correct spelling of a word and look up synonyms to add more variety to their writing.Nonetheless, learners have to be careful when using dictionaries as the lexical-semantic information contained in dictionaries might not be sufficient with regards to language production in a particular context and learners may be misled into choosing incorrect words.
