This use of the term has become common in the UK in correspondence from hospitals, e.g., "you may be accompanied for your appointment by a significant other."[citation needed] The first known use of the term is by the U.S. psychiatrist Harry Stack Sullivan in the article 'Conceptions of Modern Psychiatry' in the journal: 'Psychiatry: Journal of the biology and pathology of interpersonal relations', published in 1940.[4] The phrase was popularised in the United States by Armistead Maupin's 1987 book Significant Others, and in the UK by the 1989 TV series Only Fools and Horses, in which Derek Trotter uses the phrase a number of times when referring to his long-term partner Raquel Turner.[5] ./cache/en-wikipedia-org-1642.html ./txt/en-wikipedia-org-1642.txt
