  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.
