cack-handed: cack-handed: [19] Cack comes from a 15thcentury dialect verb meaning ‘defecate’, which probably came from Middle Dutch cacken. It goes back via Latin cacāre to an ultimate Indo- European base *kak-, from which a lot of other Indo-European languages get words connected with ‘excrement’. The connection with cackhanded is usually explained as being that clumsy people make a mess; on this view ‘left-handed’, which cack-handed also means, is a secondary sense derived from ‘clumsy’. It may be nearer the mark to place ‘left-handed’ first, however, bearing in mind the traditional role of the left hand in many cultures for wiping the anus.
milk: milk: [OE] Far back into prehistory, milk traces its ancestry to an Indo-European base *melg-, which denoted ‘wiping’ or ‘stroking’. The way of obtaining milk from animals is to pull one’s hand down their teats, and so *melg- came in due course to be used for ‘milk’. It passed into Germanic as *melk-, which formed the basis of the noun *meluks, and this over the centuries has become German milch, Dutch and Danish melk, Swedish mjölk, and English milk.

The now virtually obsolete adjective milch ‘giving milk’ [OE] (as in milch cow) goes back to a Germanic derivative of *meluks. Another derivative of Indo-European *melgwas the Latin verb mulgēre ‘milk’, which has given English emulsion and promulgate.
=> emulsion, promulgate
