Morphology

unthinkably = unthinkable (transparent) = un + think + able + ly

Formed by adding the productive adverbial suffix '-ly' to the adjective 'unthinkable', which itself is transparently built from 'un-' + 'think' + '-able'.

Etymology

Unthinkably is made from un- ('not'), think and -ably ('in a way'), so it literally means 'not able to be thought'. That's why unthinkably describes something so extreme you can hardly imagine, like an 'unthinkably' high cost or an 'unthinkably' brave act.
