Synonym discussion

Sense: adverb/1

All three synonyms intensify a negative quality beyond what is acceptable. 'Unbearably' is the most frequent choice in everyday speech and writing; it works broadly, from physical sensations (unbearably hot) to emotional ones (unbearably sad). 'Intolerably' sounds more formal and logical — it implies that the situation violates a reasonable limit (intolerably rude, intolerably slow). 'Impossibly' is milder and sometimes figurative: an impossibly tight deadline may still be met, whereas an unbearably tight one cannot be. In practice, an impossibly long lecture feels exaggerated for effect, while an insufferably long one carries sincere irritation. Choose 'unbearably' for neutral emphasis, 'intolerably' for formal or principled objections, and 'impossibly' for dramatic or less literal exaggeration.

Etymology

LatinFrenchEnglish

Built from the prefix 'in-' (not) + 'suffer' (to bear or endure, from Latin 'sufferre' — to carry under, undergo) + '-able' (capable of) + '-ly' (adverbial suffix). The word entered English through Anglo-French 'suffrir' and was first recorded in the 15th century. 'Insufferable' appeared in English around the 1530s, and the adverb form 'insufferably' followed soon after, literally meaning 'in a way that cannot be endured'.
