IPA: /ɪmˌpɒndəˈræbɪlɪti/
KK: /ɪmˌpɒndəˈræbɪlɪti/
The quality of being difficult to measure or understand; something that cannot be easily weighed or assessed.
The imponderability of human emotions makes it hard to predict behavior.
Imponderability is formed from "im-" (meaning not) and "ponderare" (meaning to weigh) combined with the suffix "-ability" (meaning the quality of being). The word refers to the quality of being unable to be weighed or measured, often used in a philosophical or abstract context.
Think of 'not weighing' ('im-' means not and 'ponderare' means to weigh) to remember that 'imponderability' refers to something that cannot be measured or weighed.
