Definition:
In literature, this device refers to the practice of joining together two or more words in order to create an entirely new word. This is often done in order to create a name or word for something by combining the individual characteristics of 2 or more other words.
Example:
1. The word “smog” is a portmanteau that was built combining “fog” and “smoke” and “smog” has the properties of both fog and smoke.
2. Liger= Lion + Tiger= A hybrid of the two feline species, possessing characteristics of both.
