Linguistic Terms comprise the cornerstone on which sciences are based, and the key by which scientists and researchers communicate and discuss various sciences. If the originator of the term suffers from one problem of choosing the appropriate term for the concept in his mother tongue, the translator undergoes the impact of a number of things that determine the image he chooses to perform the concept transmitted from other languages. This paper seeks to identify the most important problems faced by Arab researchers and scientists in the transfer of linguistic sciences from foreign languages to Arabic in a way that facilitates the contribution science building, understanding and development.
