where did the name dada come from and what does it mean
Dada There is no consensus on the origin of the movement's name; a common story is that the Austrian artist Richard Huelsenbeck plunged a knife at random into a dictionary, where it landed on "dada", a colloquial French term for a hobby horse. Others note that it suggests the first words of a child, evoking a childishness and absurdity that appealed to the group. Still others speculate that the word might have been chosen to evoke a similar meaning (or no meaning at all) in any language, reflecting the movement's internationalism.[6]
Miller (name) Miller and Millar are surnames of English language, Old English or Scottish origin. There are two homonymous forms of Miller, one that began as an occupational surname for a miller[1][2][3][4] and another that began as a toponymic surname for people from a locale in Glasgow. Miller of the occupational origin may also be translated from many cognate surnames from other European languages,[5][6] such as Mueller, Müller, Mühler, Moller, Möller, Møller, and others. There is also a form in the early English lingusitics as Milleiir.
