While Playing One Afternoon, a Group of Children Decided to Develop

While playing one afternoon, a group of children decided to develop a special language only they would know. Jordan started working on the new symbols for their thoughts and behaviours. After writing quite an elaborate letter using his new symbols he gave it to the other children to try to decipher the message. To their dismay, the same symbols were used in very different ways and different symbols often represented the same idea. Jordan had violated one of the three critical properties of language because his language:

A) was not symbolically linked
B) was generative
C) was able to produce an infinite number of messages
D) did not have a rule-governed structure
