One of the defining features of human language is the process of adding another unit - a prefix or suffix - to a word to change its meaning.

For example, adding "hood" to the word "brother" to form "brotherhood".

The team found that booms were sounded when a falling branch had been spotted or to initiate group travel.

Kraks were only given after a leopard had been sighted.

While hoks were almost exclusively sounded when a crowned eagle swooped above the canopy.

But further analysis revealed that while booms were always unaltered, the monkeys sometimes added an "oo" to their kraks and hoks - and this transformed the information they were conveying.
