Verbal language is a complex system of symbols used by communities to communicate and share meaning through interpreting and expressing messages. It has characteristics like being arbitrary, abstract, and changing over time. Semantics derives meaning from words and sentences, and can be improved with specific, concrete, descriptive language and examples. Pragmatics understands messages in context, where meaning depends on speakers and situations. Tips to improve pragmatics include telling the truth, providing relevant information, acknowledging violations, and assuming positive intent.
