Origin and usage
The noun bubble is thought to be onomatopoeic in origin; that is, the word is thought to imitate the sound of bubbling. It has been used since the 14th century.
Bubble has a number of meanings and has recently acquired a couple of new ones. In the context of the coronavirus pandemic, a bubble is a restricted area or group within which people can move and interact freely. This sense was recently added to the crowdsourced Open Dictionary, with an example referring to a possible bubble of unrestricted air travel between New Zealand, which has recently declared itself virus free, and neighbouring Australia, which is on the way to being so. An even more recent use is related to a new policy declared this week by the UK government, but applying only to England. From 13 June any household consisting of an adult living alone or with children who are minors will be able to interact with one other household without observing social distancing, and even stay overnight. This arrangement, which applies to, say, lone grandparents wishing to see their children and grandchildren, or single people wishing to see partners they don’t live with, is being referred to as a social bubble. The Open Dictionary is a brilliant way of recording new and emerging language use. You can enter your own submissions here.
