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]
Anderson (surname) Anderson is a surname deriving from a patronymic meaning "son of Anders/Andrew" (itself derived from the Greek name "Andreas", meaning "man" or "manly"). It originated in parallel in the British Isles and the Nordic countries.
