Rangy comes from range + -y; range derives from Old French range ('row, rank'), from rangier ('to set in a row'), from renc ('rank, row'), of Germanic origin. The historical chain includes Old French rangier. Older glosses in the chain include "row, rank", "to set in a row", and "rank, row", which help explain the semantic range of the modern word. Morphologically, rangy is best read as compound, suffixal formation, and borrowing, yielding an English adjective shaped by both form history and later usage. In current English it functions as an adjective, with the sense "tall, slender, and long-limbed, often suggesting agility". English derivatives include ranginess; related forms include range. The result is an English adjective whose etymology preserves the older forms while supporting the word's specialized modern meaning.
