Oh sorry, I thought it was clear. It's not an official term AFAIK. It just means that you can't reassign the variable, since you can't assign an array to another array. Basically you can't assign it another value (deleting the assignment operator would also make a type not reassignable). In this case, the new object is accessible through the result of placement new, but if you use a C style array as buffer, then you can't assign the result to that array.

Hope that makes sense :) sorry
