the.com/paper airplane

means A dart or glider folded from a flat sheet of paper, shaped and weighted to catch air and glide when thrown.

from Not a tidy coinage but a convergence of two old habits: paper folding (origami traditions in Japan and China go back centuries) and humanity's older itch to mimic flight with simple materials. The specific phrase 'paper airplane' is just as literal as it sounds — it entered common English once powered flight gave us the word 'airplane' in the early 1900s, and kids (and bored adults) promptly applied it to any folded glider. There's no single inventor or origin story — just generations of idle hands discovering that a few sharp creases and a flick of the wrist can outwit gravity, briefly.
