Irregular galaxies are a unique type of galaxy in the universe. They are characterized by their asymmetrical shapes and lack of particular structure or discernible spiral arms. Due to their unusual features, there are numerous synonyms used to describe irregular galaxies by astronomers, astrophysicists, and cosmologists. These include chaotic galaxies, amorphous galaxies, formless galaxies, undistinguished galaxies, and unstructured galaxies. The term "disturbed" is also employed as it refers to galaxies that have experienced a gravitational encounter with another galaxy resulting in the rearrangement of their stars. These diverse synonyms indicate the range of shapes and features of irregular galaxies and reflect the continuing mystery and fascination with these enigmatic objects.
