A mondegreen /ˈmɒndᵻɡriːn/ is a mishearing or misinterpretation of a phrase as a result of near-homophony, in a way that gives it a new meaning. Mondegreens are most often created by a person listening to a poem or a song; the listener, being unable to clearly hear a lyric, substitutes words that sound similar, and make some kind of sense. American writer Sylvia Wright coined the term in 1954, writing about how as a girl she had misheard the lyric "...and laid him on the green" in a Scottish ballad as "...and Lady Mondegreen".
"Mondegreen" was included in the 2000 edition of the Random House Webster's College Dictionary, and in the Oxford English Dictionary in 2002. Merriam-Webster's Collegiate Dictionary added the word in 2008. The phenomenon is not limited to English, with examples cited by Fyodor Dostoyevsky, in the Hebrew song "Háva Nagíla" ("Let's Be Happy"), and in Bollywood films.
A closely related category is a Hobson-Jobson, where a word from a foreign language is homophonically translated into one's own language, e.g. cockroach from Spanish cucaracha. For misheard lyrics this phenomenon is called soramimi. An unintentionally incorrect use of similar-sounding words or phrases in speaking is a malapropism. If there is a connection in meaning, it can be called an eggcorn. If a person stubbornly sticks to a mispronunciation after being corrected, that person has committed a mumpsimus....LESS
