ENFused words are becoming increasingly more important in term development. Fusion allows us to create new and more motivated terms while also avoiding overloading already developed terms with additional meanings. Fused words can be used to further develop derivative terms, they can also be used as components of composite terms as well as make up specific construction term microsystems. Recently, hybrid fused words have become more popular. In this article we seek to diachronically review hybrid fused words in construction terminology. As the construction area has an abundance variety of terms, it can partially represent the development of general educational language as a whole. The article discusses the relation between hybrid and indigenous fused words, analyzes the origin of borrowed compounds as well as discusses the extralinguistic factors that lead to the development of hybrid fused words and their quantity.
