IPA: /ɪnˈkæl.kjʊ.lə.bəl/
KK: /ɪnˈkæl.kjə.bəl/
Something that cannot be measured or calculated, often because it is too great or unpredictable.
The incalculable effects of climate change worry scientists around the world.
Incalculable → It is formed from "in-" (meaning not) and "calculable" (from Latin "calculabilis", meaning able to be counted or calculated). The word "incalculable" means not able to be counted or calculated, often referring to something vast or immeasurable.
Think of something that cannot be counted ('in-' means not, and 'calculable' relates to counting) — that's why incalculable refers to something immeasurable.
