The theoretical framework dealt with the linguistic vocabulary that has recently emerged in the field of interior design and how it has had distinctive meanings within its practical framework in the work of specialization such as (the other, the biology, the style) as models of vocabulary in scientific studies that proved the presence of a linkage between the language and interior design in providing a new scientific addition for a linguistic vocabulary and a philosophical term to reach its role in interior design as a specialized science that has gained its importance through its direct relationship to human life.
