copious

This word carries a sense of overflow or excess that borders on being overwhelming. It is frequently used in academic or formal writing to describe a vast amount of information, evidence, or liquid, suggesting a volume that is more than sufficient for the task at hand. While similar to abundant, copious often implies a lack of restraint or a sprawling nature. For instance, someone might take copious notes, meaning they wrote down almost everything said, whereas abundant might simply mean there were plenty of notes available.
