The term "old salt" is a charming piece of seafaring lingo that has been in use since as far back as the 19th century. This nautical slang refers to an experienced, weathered mariner or sailor who has spent much of their life at sea. The usage of 'salt' in this context is inspired by the sea's salinity. Fascinatingly, sailors were also often paid in salt, which was a highly valued commodity, hence the origin of the word 'salary'. Moreover, salt is known for its preservative properties, and such seasoned sailors, seen as 'preserved' by their sea experiences, embody the durability, resilience, and wisdom that comes with a life spent navigating the world's oceans. Thus, when someone is referred to as an 'old salt', it paints a picture of a sailor with a wealth of stories, experiences, and nautical knowledge, a true testament to their many voyages and adventures.
