Morphological freedom

Morphological freedom is a way of talking that allows people to create or change words. For example, adding a suffix (like “-y” or “-ness”) to the end of a word to change its meaning. For example, adding “-able” to the end of a word can make it mean something that you can do. So, if the word “clean” has “-able” added to it, the new word becomes “cleanable”, and it means something that can be cleaned. Morphological freedom also allows people to combine words together to create new words. For example, if you want to talk about something being able to be seen through an electronic device, you could combine the words “see” and “electronic” to make a new word, “seelectronic”.
