armored
Protected by a strong, tough covering against harm or attack.
Armored means protected by a strong covering designed to resist damage or attack. A medieval knight wore armored suits made of metal plates to defend against swords and arrows. Modern soldiers might wear armored vests to protect against bullets. An armored truck carries money or valuables, with reinforced steel walls that make it nearly impossible to break into.
Think of how a turtle's shell shields its soft body, or how thick bark protects a tree. Armored vehicles used in warfare, like tanks, have heavy metal plating that can withstand explosions and gunfire. Banks use armored cars with specially reinforced bodies to transport cash safely between locations.
You might also hear the word used more broadly: someone with an armored heart has built emotional walls to avoid getting hurt. The idea is the same: creating a tough outer layer of protection, whether physical or emotional, against potential threats or damage.
