gist: [18] Cest action gist, literally ‘this action lies’, was an Old French expression denoting that a case was sustainable in law and could be proceeded with. English took over gist, which was the third person singular of the verb gésir ‘lie’, as a legal term meaning ‘grounds for action in a suit’. The more general modern meaning, ‘central point’, developed in the 19th century.

1711, "the real point" (of a law case, etc.), from Anglo-French legalese phrases such as cest action gist "this action lies," from Old French gist en "it consists in, it lies in," from gist (Modern French g?t), third person singular present indicative of gésir "to lie," from Latin iacet "it lies," from iacere "to lie, rest," related to iacere "to throw" (see jet (v.)).
