Lexicon: dictionary, anywhere


There is no lack of dictionaries if you are connected to the internet. Browser extensions make it easier to access meanings too. However, typically the process takes a while to fetch the information. Lexicon is a native Linux dictionary that makes the whole process very fast and doesn’t need any connectivity.
