What is the meaning of the word 'copious'?

The term 'copious' is used to describe something that is very large in quantity or an excessive abundance of something. It often refers to a vast amount of something that is plentiful. For instance, when someone talks about taking copious notes, they mean they’ve written down a great many details, demonstrating that the quantity is overwhelming or excessive in nature. This aligns perfectly with the definition provided in the second choice. The other options do not capture the essence of 'copious,' as they imply limited amounts, negative social behavior, or lack of clarity, which are not related to the concept of abundance indicated by the word.
