Summary It is shown that a group may be made up of subgroups all of which are relatively compact or homogeneous. Another group may have one or more subgroups scattered among comparatively diverse members. These scattered sets are called here sibling groups. The possibility that the ranks with the prefix ‘sub‐’ arose to meet an unwritten need to accommodate sibling groups is suggested. Their use for this is briefly examined. Giving the same rank to the sibling group and its allies is shown to be misleading. A simple nomenclatural device is proposed to show the presence of sibling groups.
