inshore is a modern English compound of in (toward, near) + shore (from Middle English schore, of uncertain origin, perhaps from Old English *scora, related to scieran 'to cut'). Morphologically, the word is best read through the components named in the history, with the modern spelling preserving a compound structure rather than a single unanalyzable stem. The etymology remains cautious where the history is cautious: comparisons, echoic formation, or disputed derivation do not make the ancestry more definite than the forms actually named. In present English, the adjective sense is "situated in or moving toward the water near the shore", so the historical development ends in a clearly identifiable modern dictionary use. The same base also appears in related forms such as shore, offshore, and ashore. Its semantic neighborhood includes coastal, nearshore, and onshore, which helps locate the modern sense without adding a separate etymological claim. The named historical forms include Old English in and Middle English schore.
