Verbal-linguistic intelligence was first introduced by Howard Gardner in his book called "Frames of Mind: The Theory of Multiple Intelligences". Verbal-linguistic intelligence is composed of four components. The first component is the semantics. The semantics focuses on understanding the right meaning behind words. Some words can convey different meanings based on where they are used. However, most of the words convey a unique meaning which is independent of the text they are being used. The second component is the phonology. Phonology refers to the sound of words used together as well as their musical interaction with each other. The third component is the grammar rules of a language. Grammar is the tool used to put words together that generate a unique meaning. The last component is the use of words in the right context. Understanding the audience and their characteristics can be useful in the choice of words.
There are a few methods that can be used to improve your verbal-linguistic intelligence. First, practice journaling on a daily basis. Writing on a regular basis is an effective method to improve your verbal skills. Additionally, it improves other skills such as self-expression, conversation, self-awareness, goal-setting, and intrapersonal skills. Second, read constantly on different topics from fiction to nonfiction, science to literature, etc. Third, practice conversing with others in any situation and opportunity. This helps you to better articulate yourself in conversations. Talk to people with different viewpoints and try to challenge yourself by listening to different opinions about a topic.
