IPA: /ɪnˈsɒljʊˌbɪlɪti/
KK: /ɪnˈsɑljəˌbɪlɪti/
The state or quality of being unable to be dissolved in a liquid.
The insolubility of certain minerals makes them difficult to extract from the earth.
Insolubility → It is formed from "in-" (meaning not) and "solubilis" (from Latin, meaning able to be dissolved) and the suffix "-ity" (meaning the state or condition of). The word refers to the state of being not able to be dissolved.
Think of 'not' ('in-') being able to be 'dissolved' ('solubilis') — that's why insolubility means the condition of not being able to dissolve.
