What is the definition or description of: enlarged tonsils?

Enlarged tonsils: This is a complex question. We grade tonsil size by how large they are with respect to the tonsillar pillars. 1+ is small and in the fossa, 2+ is no larger than the fossa but to the fossas, 3 + larger than the fossa or pillars, 4+ touching each other. As we get older the tonsils should recede and get smaller. Enlarged tonsils decrease the size of the airway for breathing
