The term that is defined as the human capacity for acquiring and using complex communication systems is language. Language encompasses both spoken and written forms of communication and includes various elements such as vocabulary, grammar, and the ability to convey ideas, emotions, and concepts. It is a unique trait that distinguishes humans from other species, enabling complex social interaction and cultural expression.

While syntax refers specifically to the rules that govern the structure of sentences in a language, and linguistics is the scientific study of language and its components, these terms do not fully capture the broader concept of human communication abilities encapsulated by the word "language." Dialect, on the other hand, pertains to specific forms of language that are particular to a region or social group, but it is not representative of the entire capacity for communication that language signifies. Hence, the answer highlights the encompassing nature of language as a fundamental aspect of human communication.
