Final answer:
The use of sounds, signs, or written symbols for communication is called language, which encompasses both spoken words and written marks. It is a system of arbitrary symbols including letters, pictographs, and gestures used for expressing and sharing thoughts, feelings, and cultural norms.
Step-by-step explanation:
The systematic use of sounds, signs, or written symbols for the purpose of communication or expression is called language. Language enables the communication of thoughts and feelings through a system of arbitrary symbols known as words. These words can be vocalized or in many cases also represented by written marks. Beyond verbal language, humans also use various forms of semiotics or the communication of signs, which includes symbols like letters and pictographs, and can extend to body language and facial expressions.
All language systems, whether they are based on the English alphabet or the logographic characters of Mandarin Chinese, share basic elements that are effective for conveying ideas, which include an object, subject, and action. Through language, whether spoken or signed, people share information, express emotions, ideas, and cultural norms, thus language is vital to what it means to be human.
