Datapoint Fanakalo/Para-linguistic usages of clicks
Clicks may certainly express affective meaning. (A lateral click expresses impatience or anger; a dental click denotes sympathy.) However, Fanakalo exists in the land of clicks, and so Zulu speakers may use clicks when speaking the pidgin, but they often suppress them. Most non-Bantu speakers do not use click phonemes, replacing them by velar /k/.
