A chìguǒ (samara) is a type of dry, indehiscent fruit with a flattened, papery wing that aids wind dispersal. The character 翅 (chì) means 'wing'—referring to the thin, membranous extension—and 果 (guǒ) means 'fruit', making the compound literally 'winged fruit'. This botanical term describes fruits like those of maples, ashes, and elms, where the wing allows seeds to spin and travel farther from the parent tree.

In Chinese scientific and ecological contexts, 翅果 is used precisely to denote this morphological category—not for decorative or culinary purposes, but in botany textbooks, field guides, and environmental education. It’s rarely used in everyday conversation; learners will most often encounter it in biology classes or nature documentaries. While visually distinctive, it’s not confused with other fruit types like drupes or berries because of its defining aerodynamic structure.
