The Last Straw that Broke the Camel´s Back
«La gota que derramó el vaso
This idiom, which is usually shortened for «this was the last Straw…», means that someone, who is usually a resistant person, has reached the limit of their endurance and collapses or breaks into a mad streak.
Being the original 1677 expression, «the last feather that broke the horse´s back», this expression was originally intended to mean that cargo animals which are well known for having a high limit of endurance, would get their backs broken if even a tiny light thing as an extra feather was added. It was Charles Dickens who, in the 1800´s changed this expression into «The Straw that broke the camel´s back». If any person who is well known for having a really high endurance, is burden with more and more trouble or stress, that person would finally collapse.
