When something is crippled, it's not working properly. Your bike might be crippled by the broken front brake that won't let the wheel turn freely.
You can used the adjective crippled to talk about a broken machine or a process that's not working the way it should. It was once commonly used to describe a physically disabled person, but this has become an offensive term and should be avoided. The word crippled comes from the Old English crypel, which is related to cryppan, "to crook or to bend."
