| Közmondások | Minden kezdet nehéz.Aller Anfang ist schwer.Tévedni emberi dolog.Irren ist menschlichA pénznek nincs szaga.Geld stinkt nicht.Borban az igazság.Im Wein ist Wahrheit.Nem minden arany, ami fénylik.Es ist nicht alles Gold, was glänzt.Nincsen rózsa tövis nélkül.Keine Rosen ohne Dornen.Ha ló nincs, a szamár is jó.In der Not frisst der Teufel Fliegen.Vizet prédikál, bort iszik.Wasser predigen und Wein trinken.Hallgatni arany, beszélni ezüst.Reden ist Silber, Schweigen ist Gold.Aki mer, az nyer.Wer wagt gewinnt.Aki szelet vet, vihart arat.Wer Wind säet, wird Sturm ernten.Legjobb szakács az éhség.Hunger ist der beste Koch.Egy fecske nem csinál nyarat.Eine Schwalbe macht noch keinen Sommer.Kutyából nem lesz szalonna.Die Katze lässt das Mausen nicht.Sötétben minden tehén fekete.Nachts sind alle Katzen grau.A látszat csal.Der Schein trügt. |
