Final answer:
Frothing is the creation of a mass of small bubbles on or in a liquid. It's often caused by physical actions like stirring or can occur naturally, such as when a dog froths at the mouth due to excitement or illness.
Step-by-step explanation:
Frothing is the act of creating froth, which is a mass of small bubbles that are formed in or on a liquid. This can happen naturally or can be caused by a physical action such as blowing, shaking, or stirring. An example of natural frothing is when a dog is frothing at the mouth, which can be a sign of excitement, stress, or illness. The term can also describe something that is light and insubstantial, like airy talk that has no real value.
When referring to frothing, common synonyms include foam, lather, and spume. Conversely, antonyms such as slick, slime, and boil imply a different consistency or context. The froth on top of a cappuccino, for example, is created by aerating milk to produce a thick and creamy texture that complements the beverage, illustrating the use of the term in a positive connotation.
