What does insupportably mean?
Insupportably is a formal adverb meaning “to an intolerable or unsustainable degree.” It is used when describing a burden, difficulty, expense, situation, or behavior that is so extreme that it cannot reasonably be supported or endured. The word is more emphatic than ordinary intensifiers such as “very” or “extremely,” and it often carries a slightly literary or argumentative tone. For example, an argument can be described as insupportably personal, while a task may be insupportably expensive. Its use is uncommon in everyday conversation, but it can give formal writing a strong sense of excessive strain. The related adjective is insupportable, and the closely related form unsupportably is also in use. The standard pronunciation varies between British and American English mainly in the treatment of the vowel and consonant in “support.”

Where does insupportably come from?
Insupportably is formed in English from the adjective insupportable, which combines the negative prefix in- with supportable; the adverbial suffix -ly then creates the adverb. The adjective insupportable has long been used for something that cannot be supported, borne, or defended, while the related unsupportable follows the same basic pattern. Support comes through Old French from Latin supportare, ultimately associated with the Latin roots sub- and portare, “to carry.”
