To discharge or emit forcefully in a stream, or to speak at length in a pompous or declamatory manner. Can also refer to a projecting tube or nozzle for pouring liquids.
From Middle Dutch 'spouten' or Middle Low German 'sputen', related to 'spit'. The word originally described the forceful ejection of liquids and later extended metaphorically to describe verbose or pretentious speech.
The connection between water spouting and human pontificating isn't accidental - both involve forceful, often excessive discharge that can be difficult to stop once it starts. This metaphorical bridge between physical and verbal behavior shows how we understand speech through bodily experience.
