Avoidance speech is also practiced by speakers of some of the Bantu languages of southern Africa, including Xhosa and Zulu. Married women are forbidden from using their father-in-law’s name, or any word that has the same root or similar sound.
Bantu speakers often get around this restriction by borrowing synonyms from other languages spoken nearby. Some linguists think that is how click consonants found their way into Bantu speech: in words borrowed from Khoisan languages, which use clicks extensively.
In parts of India, a daughter-in-law is not allowed to use words that begin with the same letters as her in-laws’ names, requiring her to use a parallel vocabulary.
