**Studies** & **Definition** \\ \hline [PERSON] et al. [65] & The metaverse, as a virtual universe that maps and interacts with the real world, is considered an ideal embodied version of the Internet for the future. \\ \hline [PERSON] [77] & The metaverse is conceptualised as a future iteration of the Internet, wherein virtual and real environments converge into a unified domain. The term “metaverse” is derived from the prefix “meta”, signifying “beyond”, and the suffix “verse”, denoting “universe”. \\ \hline [PERSON] and [PERSON] [21] & The term “Metaverse” is derived from the prefix “meta” (indicating transcendence), and the word “universe” refers to a theoretical synthetic environment connected to the physical realm. \\ \hline [PERSON] et al. [78] & A frequent description of the metaverse is that it is an embodied form of the Internet. \\ \hline [PERSON] et al. [79] & Metaverse is the combination of the prefix “meta” (implying transcending) with the word “universe”, describing a conceptual synthetic environment connected to the physical world. \\ \hline [PERSON] et al. [80] & The term metaverse is a combination of the prefix “meta” (denoting “beyond”) and the suffix “verse” (abbreviation for “universe”). The metaverse denotes a completely immersive three-dimensional digital realm, as opposed to the broader notion of cyberspace, which encompasses the entirety of shared online space across all forms of representation. \\ \hline \hline \end{tabular}

**Studies** & **Definition** \\ \hline [PERSON] et al. [68] & The metaverse represents the next phase of advancement of the internet, emphasising the development of an immersive experience within the virtual world. \\ \hline [PERSON] [81] & The metaverse indicates the future advancement of internet connectivity, establishing immersive digital environments where humans, locations, and items live virtually. \\ \hline [PERSON] and [PERSON] [75] & The metaverse is a tangible manifestation of the Internet, consisting of a cohesive amalgamation of interoperable, immersive, and communal virtual environments accessible by user avatars. \\ \hline [PERSON] and [PERSON] [82] & The metaverse is catalysing the next wave of innovation by creating new opportunities through the transformation of the digital realm (Internet) into a virtual realm, characterised by a unified, immersive, and persistent three-dimensional virtual space. \\ \hline [PERSON] and [PERSON] [83] & The metaverse is the next-generation Internet, defined by immersive three-dimensional virtual settings that replicate the physical world, allowing users to participate in diverse experiences through customisable digital avatars. \\ \hline [PERSON] et al. [56] & The metaverse is a concept that facilitates the creation of an environment where individuals can experience both real and virtual worlds. \\ \hline [PERSON] et al. [84] & The metaverse is defined as a conglomeration of enduring virtual realms where users can exchange experiences at the convergence of the physical and digital domains. \\ \hline [PERSON] et al. [73] & The metaverse is a virtual version of the Internet, conceived as a singular, universal, immersive environment facilitated by virtual reality (VR) and augmented reality (AR) headsets, often pictured in futuristic and science fiction contexts. \\ \hline [PERSON] [54] & The metaverse is a network of immersive virtual worlds that intersect with reality, allowing users to interact, create, and consume content through avatars in a persistent, synchronous environment backed by a digital economy. \\ \hline \hline \end{tabular}
