noun / verb
trampoline
tram-puh-LEEN/ˌtræmpəˈliːn/
A springy fabric platform for bouncing.
The trampoline has a taut fabric bed held by springs.

Etymology
Italian trampolino meant “springboard” and came from trampoli, “stilts.” The modern fabric platform preserves the springboard idea: a yielding surface that helps a jumper rebound.
In context
