unendurable
Impossible to withstand
Unendurable means impossible to bear or tolerate—suffering or conditions so severe they exceed human capacity to withstand: The pain became unendurable.
The word is stronger than unbearable, suggesting something that simply cannot be endured rather than something merely difficult: unendurable grief, unendurable heat.
Often used for emphasis in less dire contexts: The wait was unendurable.
