Similarly, among Tajik speakers, the proverb "One hand cannot clap" has two significantly different interpretations. Most see the proverb as promoting teamwork. Others understand it to mean that an argument requires two people. In an extreme example, one researcher working in Ghana found that for a single Akan proverb, twelve different interpretations were given. Proveb interpretation is not automatic, even for people within a culture: Owomoyela tells of a Yoruba radio program that asked people to interpret an unfamiliar Yoruba proverb, "very few people could do so". Siran found that people who had moved out of the traditional Vute-speaking area of Cameroon were not able to interpret Vute proverbs correctly, even though they still spoke Vute. Their interpretations tended to be literal.
