Try the russian word пожалуйста, it can mean either please or you are welcome . it sounds something like ' poshoulster' , difficault to try to put  down in english how it sounds but its an easy word to say when you know it . There are lots like it but itsa good example of one word replacing many in the english language . ' you are wlcome ' all condensed down to that one word . Interesting language,(reply>), Пожалуйста can be transcribed as Pozhaluycta
