Morphology is basically the study of words, how they are formed and their exact relationship to other words in different languages. It is of great use for people who see to understand different languages. Linguists find it incredibly useful. There are many books on the subject as well which allows you to translate between different languages in order to communicate better.
Nowadays, there are many apps that can also do this for you allowing immediate translation for faster communication. You simply type in the word and the app translates it into any other language of your choice to make conversations easy.
