Final answer:
The structure of language includes elements like phonology, morphology, syntax, and lexicon, which are integral to its composition. Kinesics, however, is not a component of spoken or written language structure; it pertains to non-verbal communication.
Step-by-step explanation:
When analyzing the structure of language, we consider several elements that are essential to its composition. Among these, we include elements like phonology, which is the study of the sound systems and patterns in a language. Phonology encompasses phonemes, the smallest units of sound that can distinguish meaning.
Another essential element is morphology, which refers to the structure and construction of words. This includes understanding how morphemes, which are the smallest grammatical units in a language, are combined to form words. Syntax is also a critical component, as it pertains to the arrangement of words and phrases to create well-formed sentences according to a particular language's rules. The lexicon, or the vocabulary of a language, is also a key structural element.
However, kinesics, which is the study of body language and gestures, does not fall within the traditional structure of spoken or written language. Kinesics is more related to non-verbal communication and is therefore not considered a component of language structure in the context of this question.
