Recently, significant attention has been drawn to the development of two emerging antenna technologies known as "Fluid Antenna" and "Movable Antenna" in wireless communication research community, which is greatly motivated by their unprecedented flexibility and reconfigurability for improving system performance in wireless applications. However, some confusions have also ensued on their nomenclature. In fact, both "Fluid Antenna" and "Movable Antenna" are not newly-made terms, and they have a longstanding presence in the field of antenna technology. This article wishes to provide some clarity on this closely related terminology and help dispel any confusion, concern or even dispute on the appropriate use of their names in the literature. Our hope is to unite researchers and encourage more research endeavours to focus on resolving the technical issues on this topic. This article begins by reviewing the historical evolution of these technologies for fostering a clear understanding of their origins and recent development in the realm of wireless communication. We will conclude this article by commenting on other nomenclatures that have emerged in the recent research of Fluid/Movable Antenna.
