äraarvatav

äraarvatav is an Estonian adjective that translates to "unpredictable" or "incalculable" in English. It describes something that is impossible to foresee, guess, or calculate beforehand. This can apply to various situations and phenomena.

For example, the weather can be äraarvatav, meaning its changes are difficult to predict accurately. Similarly, a person's behavior might be described as äraarvatav if they act in ways that are surprising or inconsistent. The term can also be used in contexts where the outcome of an event is uncertain or beyond human control, such as the results of a complex experiment or the course of a disease. In essence, anything that defies a clear expectation or rational estimation falls under the umbrella of äraarvatav. The opposite of äraarvatav would be predictable or calculable.
