Fady

Fady is not strictly a taboo, it is more a belief which signals when something is "dangerous" related to action, food, locations etc. The Malagasy word fady (pronounced fahdy) is of Indonesian origin.

Fady (noun): Abstinence, fasting, prohibition; unlawfulness, incest; anything tabooed. It often takes an accusative case, as: fady ahy izany. Faly is used in the provinces. (Richardson 1885)
