Like in English where one encounters fixed phrases like "to
take into account", German, particularly scholarly and
scientific German, possesses certain fixed noun-verb combinations
which usually feature a particular preposition as well.
Examples:
auf Probleme stoßen (to run into
problems)
in Schwierigkeiten geraten (to get into
trouble)
in Erwägung ziehen (to take into
consideration)
zum Abschluss bringen (to bring to a
conclusion)
zum Abschluss kommen (to come to a
conclusion)
in Brand setzen (to set on fire)
unter jemandes Einfluss geraten (to fall under
someone’s sway)
