Fully sufficient; found in copious supply; in great quantity; overflowing.
"The river was so abundant that it overflowed its banks, creating a vast expanse of water across the valley floor."
In plain English: Having more than enough of something so that you do not need to worry about running out.
"The garden was abundant with wildflowers after the heavy rains."
Usage: Use abundant to describe something that exists in large quantities or is more than enough, such as an abundant harvest of fruit. It often serves as a stronger synonym for plentiful but emphasizes overflow rather than just adequacy.
The word "abundant" comes from the Latin verb abundō, meaning "to overflow." It entered English through Middle English and Anglo-Norman around 1380, originally describing something that flows over in great quantity.
