It looks like DDG is using wordnik as their source for definitions.

For this word they have four definitions each with a different license:

1. Formally all rights reserved but now out of copyright and in the public domain
2. GPL-2 (but based on an out of copyright proprietary dictionary)
3. CC BY-SA 4.0
4. Alll rights reserved

Of these licenses the first is the easiest to work with. It comes with the fewest restrictions and transfers the fewest responsibilities to downstream consumers.

The OP definition is available in context here:
