offshore

The compound word "offshore" is a transparent combination of two native English elements. The adverb/preposition "off," from Old English of, meaning "away" or "from," is prefixed to the noun "shore," from Middle English schore, which itself likely derives from Old Dutch or Middle Low German, meaning the land at the edge of a sea or lake. The literal, spatial meaning "away from the shore" or "situated at a distance from the coast" emerged logically from this combination. This concrete geographical sense was later extended metaphorically into the financial and commercial domain in the mid-20th century, where "offshore" describes entities or transactions located "away from" or "at a distance from" a home country's regulatory and tax jurisdiction, mirroring the physical sense of being removed from the mainland shore.

Structure: off + shore - off (Old English): A preposition/adverb/adjective-forming prefix meaning "away, from, or at a distance." - shore (Middle English): A noun meaning "land bordering a large body of water."
