They go, but are overwhelmed by an avalanche, while the wife and the huntsman escape unharmed. This business of the avalanche is treated by the critics as something quite inenubilable. Yet what could be plainer than [Henrik] Ibsen's meaning?
Where it comes from
From English in- (prefix meaning ‘not’) + Latin ēnūbilāre (“to clear of clouds or mist; (figurative) to clear of obscurity”) + English -able (suffix meaning ‘able to be done’ forming adjectives), possibly coined by the English critic and essayist Max Beerbohm (1872–1956): see the 1903 and 1911 quotations below. By surface analysis, in- + e- + Latin nubil- + -able. Ēnūbilāre is derived from ē- (a variant of ex- (prefix denoting privation)) + nūbilus (“cloudy, overcast; (figurative) beclouded, confused, troubled”) (from nūbēs (“cloud; (figurative) concealment, obscurity”), ultimately from Proto-Indo-European *(s)newdʰ- (“to cover”)) + -āre.
