Pawn Island
A group of one or more pawns of the same color that is separated from other such groups by at least one fully open file.
Having fewer, larger pawn islands is generally considered structurally healthier than having many small islands, since scattered pawns are harder to defend and coordinate.
Etymology
No coinage, coiner, or first citation for pawn island was located in any source fetched, so the historical fields are left unfilled rather than filled with a guess. The metaphor is transparent, a group of pawns surrounded by empty files as an island is surrounded by water, but no lexicographic source consulted traces it. Wikipedia's chess glossary defines a pawn island as a group of pawns of one color on consecutive files with no other pawns of the same color on an adjacent file, and adds the useful boundary case that a pawn island consisting of one pawn is an isolated pawn. Edward Winter's compilation of earliest occurrences of chess terms contains no entry for the expression. Editors should present it as descriptive terminology of undocumented origin.
