6. Etymology: nothing suggests great abundance more vividly than overflowing waves; and that is the literal meaning of the word abundance.

In Latin, unda means "wave", poetically "sea". The Romans combined ab, "from", and unda into the word abundare, "to overflow"; literally, "to come from the waves" or "from the sea"; applied to anything very plentiful.

The stem of abundare resulted in the English verb "to abound", and a derivative provided the noun abundance. Inundate, "to flood", also comes from unda, as does undulate, "to move like the waves".
