Extramural English (EE) is a term used in the field of second language acquisition and an example of informal learning of English. The term was first coined in 2009 by Pia Sundqvist. It refers to 'English outside the walls' (from Latin extramural, where the prefix, extra, means 'outside' and the stem, mural, means 'wall'). EE is English that learners come in contact with or are involved in outside the walls of the classroom, often through streaming media and online games.
