Questions & Answers about Sentía un cansancio de mil demonios por el calzado.
How does the phrase un cansancio de mil demonios work to mean "a hellish exhaustion"?
Can I use the intensifier de mil demonios with other nouns?
Why does this sentence use por instead of para for "because of"?
Por is the standard preposition to express the cause, reason, or motive behind an action or feeling. Since the footwear is the cause of the exhaustion, we use por el calzado. If you used para, it would bizarrely suggest you were feeling exhausted in order to benefit the footwear!
