As you can see, word formation is important as it allows language learners to increase their knowledge of word classes and helps them to increase their vocabulary base.
Today's mini-game is " word formation, " where you say names of countries, characters from the Four Great Classical Novels, and so on while doing the squat.
Such compounds are also called synthetic compounds, because in addition to compounding, the process of word formation also involves derivation (from verb to noun, e.g. from drive to driver).
They obey the same word formation rule and share the same semantic information: each is attached to an adjective as a prefix, and each has the meaning of " negative."
