seadog (English)

Where does "seadog" come from?

The word "seadog" is a straightforward compound of the English terms "sea" and "dog." While "sea" traces back to ancient Germanic and Indo-European roots describing bodies of water, "dog" originates from the Old English "docga," a term of mysterious origin that eventually replaced "hound" as the general name for the species. Together, these words merged to colorfully describe various maritime entities, ranging from experienced sailors and harbor seals to specific nautical weather omens.
