ugostiti

1. to host; to entertain as a guest
   Komšije su nas ugostile kafom i kolačima. — The neighbours treated us to coffee and cakes.
   Baka nas je lepo ugostila kad smo došli u selo. — Grandma welcomed us warmly when we came to the village.
2. (of a city, club, event) to host
   Beograd će sledeće godine ugostiti Evropsko prvenstvo. — Belgrade will host the European Championship next year.
   Partizan je u subotu ugostio Vojvodinu. — Partizan hosted Vojvodina on Saturday.

What the guest is treated to goes in the instrumental: ugostiti koga ručkom.
