The origin of the word lost can be traced back to the 1300s. The word means “wasted, ruined, spent in vain“. Perhaps more in keeping with the meaning of the idiom would be the use dating back to the 1500s. Meaning “no longer to be found, gone astray.”
It is generally used as an adjective to describe an object but can be related to a feeling or connection.
