IPA: /ɪmˈpɒndərəbl/
KK: /ɪmˈpɒndərəbəl/
Something that cannot be measured or evaluated accurately, often because it is too complex or abstract.
The effects of climate change are often seen as imponderable, making it difficult to predict future outcomes.
Imponderable → It is formed from "in-" (meaning not) and "ponderare" (meaning to weigh). The word describes something that cannot be weighed or is difficult to assess in terms of weight or significance.
Think of something that is 'not' ('in-') able to be 'weighed' ('ponderare') — that's why imponderable refers to things that are hard to measure or assess.
