When you lose something you say lost sth or you faced with loss of sth.
These are few examples with use of word loss
I lost my pen.
he lost his purse.
He had a loss of fortune before he established his new company.
avoiding loss of time.
he will be a great loss to many people
he was at a loss for words
He faced the loss in the share market.
My doubt is when we use the word loss do we have any idiomatic usage.
which of the following is idiomatic in usage
loss of vigor (I believe this is correct)
loss in vigor(I felt this is awkward but was not sure to condemn this usage.)
Please explain?
