Language has changed over time due to social class, religion, and many other features. There are two different word formation processes called derivation and compounding. Compounding is a type of word formation that involves taking two or more lexemes, combining them, and forming a new word. Every compound word can be put into two categories, endocentric and exocentric. Endocentric words are compound words that have a head. An example of this would be bottle factory. The head of the word is factory and this compound words is describing a type of factory. Another type of compound words is exocentric. Exocentric words are always nouns. These words do not have a head and there is no category to the word. An example would be hot dog. Hot dog is not describing a type of dog; it is just two words put together. Many slang words over the generations have been created using this word formation. Compounding is one of the most widespread ways of creating new words and this can be seen in slang words. Slang has both endocentric and exocentric words. Slang as defined by Merriam Webster dictionary is, “an informal nonstandard vocabulary composed typically of coinages, arbitrarily changed words, and extravagant, forced, or facetious figures of speech.” Examples of slang words that have been created through compounding are hangry, Spanglish, deadass, baby daddy, sugar daddy, baby momma, badass, frenemy, bromance, and low key. Looking at the examples I gave, each word seems to combine two words in order to create a “simpler” word that is than used to describe someone. A person who is hangry means the person is so hungry, they are angry. Although this can not be used to describe every slang word’s word formation, this can help to see how so many slang words have come to be.
