dienst = bereit, ferne = elend, frust = erlebt, funk = element, kenia = cdu, match = goethe, minister = greifen, patient = panik, planen = anlegen, proteste = probem, rtl = ard, total = mord, venedig = einnahme, virus = stille, zahlen = geliebte
entire = all, midwest = greatest, pension = prison, threat = defeat, thursday = birthday, widow = pretty, women = joke
