Quick answer
The season between summer and winter, when leaves change colour and fall.
Autumn is the season between summer and winter, when the days get shorter, the weather gets cooler and the leaves of many trees change color and fall. It lasts from September to November in the northern half of the world. In American English, people also call it fall. Farmers gather their crops in autumn, and schools begin a new year. The n at the end of the word is silent, but it comes back in the adjective autumnal.
