When it comes to polo-players, here are some collective nouns that can be used to identify and group them together: 1. Team: In the sport of polo, players form teams that compete against each other. Therefore, the term team is commonly used to refer to a collective group of polo-players. 2. Squad: This term is often employed to describe a group of individuals who have been selected together for a particular purpose or task, such as playing polo. It signifies the unity and cooperation among polo-players on the same side. 3. Ensemble: This collective noun indicates a group of people or objects that are regarded as a whole and work together harmoniously. In the context of polo-players, an ensemble refers to the combination of players who come together to form a competitive unit in matches. 4. Cavalry: Derived from the military term referring to a group of soldiers on horseback, cavalry can be used creatively to describe a collective group of polo-players, showcasing the athleticism and horsemanship skills associated with this exciting sport. 5. Troop: Typically associated with a group of soldiers or scouts, troop can also be used figuratively for polo-players, reflecting the camaraderie, discipline, and strategic coordination displayed by these athletes on the field. 6. Herd: Although the term "herd" is usually associated with animals, it can be whimsically employed to describe a large group of polo-players on horseback, paralleling the rhythmic movements and unity exhibited during a fast-paced polo match. Remember, while the above collective nouns suitably capture the essence of polo-players grouped together, the specific collective noun used may vary depending on the desired context and mood one wishes to convey.
