Definition of bubble

The origin of the word "bubble" is unclear, but it is believed to have been in use since the 15th century. One possible theory is that it comes from the Old English word "bubbl", which referred to a frothy or foamy liquid. This could have been influenced by the Latin word "bullire", meaning "to boil", which is also related to the concept of bubbles. Another theory suggests that the word "bubble" comes from the Middle English word "bobbl", which was used to describe a toy made of soap or other material that was blown into and shaped like a ball. This etymology is supported by the fact that the word "bubble" was originally used to describe the act of blowing or blowing up something, rather than the bubbles themselves. It's worth noting that the modern word "bubble" is likely a combination of both of these etymologies, with the connotation of a light, airy, and ephemeral substance that can be easily blown and popped.
