recoillessadj.

Brit.

/rᵻˈkɔɪlləs/,

/ˈriːkɔɪlləs/, U.S.

/rəˈkɔɪ(l)ləs/,

/riˈkɔɪ(l)ləs/

Origin: Formed within English, by derivation. Etymons: recoil n., -less suffix.

Etymology: < recoil n. + -less suffix.

1. Having no or little recoil, not subjected to or affected by recoil; spec. (of a firearm or piece of ordnance) having the recoil reduced, typically by deflection of the combustion gases to the rear.
