IPA: /rɪˈkɔɪləs/
KK: /rɪˈkɔɪləs/
An adjective describing a type of weapon or firearm that is designed to reduce or eliminate the backward movement (recoil) when it is fired.
The soldiers were trained to use the recoilless rifle effectively during combat.
Recoilless → It is formed from "re-" (meaning again or back) and "coil" (from Old French *coiler*, meaning to roll or wind) and "-less" (meaning without). The word describes something that does not roll back or has no recoil.
Think of something that does not roll back ('coil') and has no backward movement ('re-') — that's what recoilless means.
