Let's suppose you are a hard-core polyglot and also have a Samsung device. If that is the case then you might be interested in an application like Samsung Dictionary, developed by the South Korean company and which supports text insertion in a wide range of languages.
An application for managing dictionaries
This application allows us to insert new words into each of the dictionaries that are managed by the app. Thanks to this function the Samsung smartphone keyboard will have no trouble recognizing them. This is really useful if you are used to inserting text in different languages on a regular basis.
To access the range of dictionaries available just go to the options offered by the application and from the dictionary manager download those that you are interested in, because they are not all downloaded by default.
This is yet another application within the Samsung eco-system, which equips its devices with a complete environment of functions.
