extimacy
nounUS, UK /ˈɛkstɪməsi/
Etymology Calque of French extimité + English -cy (suffix forming nouns of condition, quality, or state). Extimité was coined by the French psychiatrist and psychoanalyst Jacques Lacan (1901–1981) in 1959–1960), probably from a blend of French externe (“external”) + intimité (“closeness, intimacy”). By surface analysis, extim(ate) + -acy.
