The narrow limits of the apparatus criticus in the new Clarendon Press edition have excluded these suggestions, which may find a place here:

I xxix, 4 Quaedam (nomina) etiam facta sunt ex nominum deriuatione, ut a prudentia ‘prudens ’; quaedam etiam ex uocibus, ut a garrulitate ‘garrulus.’ Although garrulus is the traditional reading, the derivation elsewhere (X 114) of garrulus from graculus, ‘a jackdaw,’ suggests that we may read here ut a garrulitate ‘graulus.’ For the jackdaw's name in Late Latin developed from gragulus to graulus (Fr. grolle).
