Language acquisition is a fundamental aspect of human development and has been the subject of extensive study across multiple disciplines, including linguistics, cognitive science, psychology, and education. Understanding how individuals acquire language, whether their first language (L1) or a second/foreign language (L2), is crucial for the development of effective teaching methodologies and learning environments. This paper provides an in-depth examination of the primary theories that attempt to explain the process of language acquisition. The Behaviorist Theory, pioneered by B.F. Skinner, emphasizes imitation, reinforcement, and habit formation. In contrast, the Nativist Theory, led by Noam Chomsky, argues for an innate, biological capacity for language learning, proposing the existence of a “language acquisition device” (LAD). The Cognitive Theory, influenced by Jean Piaget, highlights the role of mental processes and developmental stages in language learning, while the Social Interactionist Theory, associated with Lev Vygotsky, stresses the importance of social context and interaction in the acquisition of language.

Social media has revolutionized communication, influencing language in various ways. Online platforms encourage linguistic innovation, introduce new slang, and reshape grammar and spelling norms. While social media fosters global communication and promotes linguistic diversity, it also raises concerns about the simplification of language and the decline of formal writing skills. This paper explores the impact of social media on language evolution, its effects on communication styles, and the balance between linguistic creativity and language preservation.

This study investigates the utilization of nano-composite hydrogels for the removal of methyl violet from aqueous solutions, leveraging a Fenton-like reaction mechanism. The nano-composite hydrogel demonstrated exceptional efficiency in dye removal, attributed to the synergistic effects of the hydrogel matrix and the catalytic activity of embedded nano-particles. This process generates hydroxyl radicals under mild conditions, leading to the effective breakdown of various industrial dyes. The kinetics of dye removal, the reusability of the nano-composite, and the influence of operational parameters such as different amounts of nano-composite, pH, , temperature, and dye concentration were systematically explored. The findings underscore the potential of nano-composite hydrogel as a promising, environmentally friendly solution for wastewater treatment and dye removal.
