completely uncertain or left unresolved
The origin of the idiom "up in the air" can be traced back to the early 1800s and is related to the concept of objects or ideas being suspended or floating without a clear resolution. The phrase likely draws inspiration from the imagery of things that are physically elevated or airborne, which symbolizes uncertainty and unpredictability. It gained popularity in the early 20th century, coinciding with the advent of aviation and the fascination with flight. It is commonly used when discussing plans, decisions, or events that lack a clear resolution or definitive outcome.
