When acquiring knowledge in science, mathematics, history and art, we use language as a tool for understanding or communicating certain concepts. Language consists of vocabulary - a set of words that a person can use to communicate these concepts. If we consider living without any language, would we still know what we know? The answer is most likely no. Naturally, as vocabulary is part of a language, it also plays a vital role in understanding and communicating these concepts. However, to what extent can we say that it actually shapes our understanding of these concepts? Is it justified to say that lack of vocabulary implies lack of knowledge? If knowledge can be acquired without using vocabulary, does vocabulary only shape our communication of knowledge and not exactly its acquisition? If we rely solely on vocabulary to shape what we can know, it can limit our understanding. of certain concepts because, essentially, not all humans have complete knowledge of the words or the contexts in which they can be used. If one does not have a thorough understanding of the vocabulary, the knowledge gained from using it may be incomplete. For example, psychobabble, when people use commonly used psychological terminology to describe something vaguely related to the term. For example, “I'm very OCD about my food,” while the person should only be concerned with the taste of the food, they may not realize how serious a disorder they are referring to. Because the context in which they use words may be loosely related to the true meaning, they show an incomplete understanding of the word and what it represents. On the other hand, if a psychologist refers to...... middle of paper ...... this knowledge is complex. Let's just imagine that knowledge is water and a bottle as vocabulary. You can circulate the water in the bottle or pour it into a glass or other container according to your preference. The container can only change the form in which the water is fixed, but it cannot change its quantity or essence. The essence is the same, only the physical form differs. Likewise, the amount we drink is limited by the amount the container can hold. So if we drink only from a vessel of knowledge and not from an ocean, what we can know will remain limited.Works Cited1.
