those aspects of meaning and use for which context of use is an important factor by using the methods and goals of formal semantics. The study of the role of pragmatics in the development of children with autism spectrum disorders or developmental language disorder (DLD). Ambiguity Ambiguity refers to when it is difficult to infer meaning without knowing the context, the identity of the speaker or the speaker's intent. For example, the sentence "You have a green light" is ambiguous, as without knowing the context, one could reasonably interpret it as meaning: the space that belongs to you has green ambient lighting; you are driving through a green traffic signal; you no longer have to wait to continue driving; you are permitted to proceed in a non-driving context; your body is cast in a greenish glow; you possess a light source which radiates green; or you possess a light with a green surface. Another example of an ambiguous sentence is, “I went to the bank.” This is an example of lexical ambiguity, as the word bank can either be in reference to a place where money is kept, or the edge of a river. To understand what the speaker is truly saying, it is a matter of context, which is why it is pragmatically ambiguous as well. Similarly, the sentence "Sherlock saw the man with binoculars" could mean that Sherlock observed the man by using binoculars, or it could mean that Sherlock observed a man who was holding binoculars (syntactic ambiguity). The meaning of the sentence depends on an understanding of the context and the speaker's intent. As defined in linguistics, a sentence is an abstract entity: a string of words divorced from non-linguistic context, as opposed to an utterance, which is a concrete example of a speech act in a specific context. The more closely conscious subjects stick to common words, idioms, phrasings, and topics, the more easily others can surmise their meaning; the further they stray from common expressions and topics, the wider the variations in interpretations. That suggests that sentences do not have intrinsic meaning, that there is no meaning associated with a sentence or word, and that either can represent an idea only symbolically. The cat sat on the mat is a sentence in English. If someone were to say to someone else, "The cat sat on the mat," the act is itself an utterance. That
