The text explores the distinction between non-verbal communication, often observed in animals, and verbal expression, which is a uniquely human attribute. The author defines speaking as the use of words, emphasizing that a true word cannot exist in isolation but must be an integral component of a specific language system. Language is presented as a dynamic phenomenon shaped by a living linguistic community. This community influences not only the selection of vocabulary but also morphological changes, such as declension or conjugation, and the formation of customary word pairings and phrases. The work reflects on the mutual relationship between the individual speaker and the broader sociolinguistic context in which language evolves and stabilizes. A key element is understanding the word as an entity that gains meaning and form only within a structured linguistic whole and through active use within a community. This distinguishes human speech from mere signaling or instinctive expressions of emotion found in the animal kingdom, highlighting the systemic nature of human communication and its reliance on social convention.
