daub: [14] The ultimate source of daub, Latin dēalbāre, meant literally ‘whiten’. It was derived from the adjective albus ‘white’, ancestor of English albino and album. It developed the specific meaning ‘cover with some white substance, such as whitewash or plaster’, and by the time it reached English, via Old French dauber, it referred to the applying of a coating of mortar, plaster, etc to a wall. This was generally a messy process (particularly in the smearing of a mixture of mud and dung on to a framework of laths to produce wattle-and-daub walls), and led in due course to the broader sense ‘apply crudely’.
