asesino
/aseˈsino/ · A1 · adj
murderous, homicidal
🗡️ asesino = assassin with the double s halved and an -o on the end
Both words come from Arabic hashshashin, the medieval sect known for targeted killings. Spanish kept one s per slot: a-se-si-no. As an adjective it means murderous; as a noun, killer or murderer.
