von gestern

== German == === Etymology === Literally, “of/from yesterday”. === Adjective === von gestern (indeclinable, predicative only) (idiomatic) outdated (idiomatic, chiefly in negation) born yesterday ==== Usage notes ==== The two senses are contradictory. Sense 1 is based on yesterday meaning “of the past” (and hence “obsolete”), whereas sense 2 is based on the same word meaning “recent” (and hence “inexperienced”). This may lead to some confusion, though rarely to actual misunderstandings.
