Where does reinforced come from?
Reinforced comes from the verb reinforce, which was borrowed from French reinforcing the Latin roots re-, meaning again, and fortis, meaning strong. The Latin word fortis is the source of English words such as fortify, fortress, and fortitude. Reinforce developed in English in the sense of strengthening or making more secure, and its past participle reinforced became common as an adjective for materials or structures that have been made stronger.
