Blending (telescoping) is the process of merging parts of words into one new word, e.g. Bollywood < Bombay + Hollywood, antiégé < anti + protégé, brunch < breakfast + lunch, Mathlete < Mathematics+ athlete.
Blending has been known since the 15th c. First blends were of comic or mysterious nature as these were charades for readers or listeners to decode. Telescoped words are found in the works by W. Shakespeare (trimpherate < triumph+ triumvirate), E. Spencer (wrizzle < wrinkle + frizzle). The term portmanteau word was coined by Lewis Carroll in Through the Looking-Glass in 1872 to explain some of the words he made up in the nonsense poem Jabberwocky, e.g. galumph < gallop + triumph, chortle < chuckle + snort.

Contractions, abbreviations, and acronyms are all shortened forms of words, but there are differences in length. A contraction is a combination of two or more words that create a new, shorter word. An abbreviation is a shortened form of one word or phrase, and an acronym is an abbreviation formed from the initial letters of a group of words.
