                 Machines and humans are dynamically related. The existence of machines is not possible without human innovation and
                 efforts and the purpose of machines fails if they don’t fulfill human needs. Machines are designed to perform specific
                 tasks to ease the work of humans, but they lack the understanding and adaptability of humans, which can lead to
                 difficulties in communication, understanding and comprehension.
                 Human-machine interaction relies on words that may not always be intuitive or user-friendly, leading to frustration, or
                 inefficiency on the part of humans. Therefore, an interface that effectively bridges the gap between human intuition and
                 machine functionality is crucial for enhancing interaction and usability.


                        Challenges of the Human Language

                 Linguistics is a study of how to strategically apply language principles and practices to achieve specific aims or purposes.
                 Linguistics is widely applied in marketing, advertising, communication, education, natural language processing, and other
                 fields.  Understanding  how  language  works,  (including  structure,
                 semantics,  pragmatics,  and  sociolinguistics)  enables  individuals
                 and organisations to modify messages, improve communication,
                 and impact behaviour.
                 Understanding human language is a difficult task, especially for
                 those who have grown up around it. Human language is extremely
                 complex, with strange expressions that appear to contradict one
                 another, vocabulary that takes cultural knowledge to understand,
                 and grammatical patterns that may turn simple  statements into
                 complex expressions or tongue twisters. Machines require systems
                 known as Natural Language Processing (NLP) to understand human language.
