The word "seagoing" is formed from two components: "sea" and "going".
The term "sea" traces back to the Old English word "sǣ", meaning "saltwater, lake". This word has its roots in the Proto-Germanic language, where it was derived from the Proto-Indo-European root "*mori", meaning "sea".
The word "going" is derived from the Old English word "gān", which means "to walk, go". Its origins can be traced back to the Proto-Germanic word "*gāną", meaning "to go, walk".
When these two components are combined, "seagoing" refers to the ability to go or travel on the sea. The term is typically used to describe ships or vessels designed and equipped for travel on the open ocean.
