Final answer:
The artists and writers of the Dada movement chose the word 'Dada' based on its meaning in both French and German, which represented their rejection of logic, embrace of chaos, and criticism of societal values and norms.
Step-by-step explanation:
The artists and writers of the Dada movement chose the word 'Dada' based on its meaning in both French and German. Richard Huelsenbeck and writer Hugo Ball looked at a French-German dictionary and found that 'Dada' meant 'rocking horse' in French and 'foolish naivete' in German. They believed that this word accurately represented their movement, which aimed to reject logic, embrace chaos, and criticize the societal values and norms of the time.
