Origin
From Middle French collision, from Latin collīsiō (“clash, concussion, collision”) (whence -ion (noun suffix denoting action, result, process, state, condition)), from collīsus (“clashed together, conflicted, contended”), past participle of collīdō (“to clash, strike, dash, beat, or press together”) (whence collide), from con- (“together”) + laedō (“to strike, collide, hurt”) (whence col- (assimilated form of com-)).
