两种情况下，在布罗卡失语症和语言障碍的情况下，患者所说的语言都是不恰当的句子。这是因为病人由于损伤无法说出正确的句子。他们不能使用像“is”或“are”这样的电报。因此，他们通常最终混合了错误的句子(Linebarger,et al .，1983)。因此，患有这两种疾病的人，可能会成为语言障碍的牺牲品。语言是一种创造性的系统，它是由其他系统的组合而形成的。在对比语法中，可以将语法定义为一组规则，这些规则用于组合不同类型的离散。因此，患有布罗卡失语症和特殊语言障碍的人都有丧失使用语言的能力。
Both pidgin languages and specific language impairment is a neurological disorder and are related to the nervous system in some or the other way.
Pidgin Language may be defined as the form of speech which is used by the people who are suffering from Broca’s aphasia where they can’t communicate and the language used by SLI (Specific Language Impairment) children’s is required because they are unable to communicate with each other.
The language of the child with SLI is not clear due to the malfunctioning of the brain which is similar to the one used by the patients of Broca’s aphasia. In both these diseases the person is not able to process the language and use it to express his or her ideas.
Both, in case of Broca’s aphasia and SLI impairment the person knows what to speak or whatever he or she wants to express but he or she fails to express the same as he/ she can’t pronounce the correct word or sentence.
Both, In case of Broca’s aphasia and SLI impairment the phenomenon of expressing the language in the form of the speech is severely reduced. Due to this the patient is not able to expresses whatever he or she wishes to speak. They are generally unable to express their feelings.
Both, in case of Broca’s aphasia and SLI Impairment, the language which is spoken by the patients consists of improper sentences. This is because the patients are unable to speak the proper sentences due to the impairment. They are not able to use the telegraphs such as “is” or “are’. Thus they generally end up mixing the wrong kind of sentences (Linebarger, et al., 1983). Thus the people who are suffering from either of the two diseases can fall prey to the language impairment. Language is nothing but a creative system which is formed out of the combination of the number of other systems. On the contrast grammar may be defined as the set of rules which is used for the purpose of the combination of the different kinds of discrete. Thus, both the people who are suffering from Broca’s aphasia and SLI impairment suffers from the loss of ability to use the languages whenever required.
