A game framework is a library designed to help game development. It usually defines APIs to deal with graphics, sound, user input, data files, etc. In most cases it defines a high-level API that allows cross-platform development.
Main difference between game frameworks and game engines is that the later also implements the game loop, as well as complex data structures (maps, actors...), data containers and tools.
