Use the adjective unendurable to describe situations that are truly impossible to bear, like the unendurable pain of losing a beloved friend. You can also use the word to emphasize the negative qualities of something: "This math class is unendurable — I'm transferring to modern dance." When you can endure something, you can stand it, even if it's hard. Endure comes from the Latin indurare, "make hard" or "harden the heart against."
