Pemex is the Mexican state-owned petroleum company managed and operated by the Mexican government. It was formed in 1938 by nationalization and expropriation of all private oil companies in Mexico at the time of its formation. Pemex had total assets worth $101.8 billion in December 2019 and as of 2009 was Latin America's second largest enterprise by annual revenue, surpassed only by Petrobras. The company is the seventh most polluting in the world according to The Guardian.

In linguistics, a blend—also known as a blend word, lexical blend, or portmanteau—is a word formed, usually intentionally, by combining the sounds and meanings of two or more words. English examples include smog, coined by blending smoke and fog, as well as motel, from motor (motorist) and hotel. The component word fragments within blends are called splinters.
