What Does “A Wrack of Rabbits” Mean?
“Wrack” is one of the rarer, less certain collective nouns on this list, and we want to be upfront that we can’t confirm its exact origin. One plausible connection is the old English sense of “wrack” meaning ruin or destruction, the same root behind the phrase “wrack and ruin.” If that link holds, the term may reference rabbits’ long-standing reputation as prolific, destructive grazers, capable of stripping vegetation and damaging crops and gardens when populations go unchecked.
That reputation is genuinely earned in some contexts; rabbits’ rapid breeding, a single pair’s descendants can theoretically number in the hundreds within a couple of years under ideal conditions, has made uncontrolled rabbit populations a real agricultural and ecological problem in various parts of the world, most famously following their introduction to Australia in the 19th century. We’re presenting the destruction-related origin as a reasonable possibility rather than settled fact, since a fully documented source wasn’t something we could verify.
Example: “The farmer surveyed the stripped vegetable patch and blamed the wrack of rabbits that had been raiding it nightly.”
