Latin, literally "in the midst of things," from medias, accusative fem. plural of medius "middle" (see medial (adj.)) + accusative plural of res "a thing" (see re). From Horace, in reference to narrative technique:
Semper ad eventum festinat, et in medias res,
Non secus ac notas auditorem rapit (etc.)
in extremis
in facie curiae
in fieri
in forma pauperis
in loco parentis
in medias res
in memoriam
in re
in situ
in totidem verbis
in toto
