What does throttled mean?
Throttled is the past tense and past participle of throttle, and it describes something whose speed, flow, capacity, or operation has been deliberately restricted. Its most familiar use is mechanical: an engine or jet may be throttled back to reduce power, while a valve or fluid line may be throttled to control the amount passing through it. The word also has older and figurative senses involving choking, silencing, or suppressing something. In everyday discussion, saying that a person, organization, or project has been “throttled” usually suggests that its activities or resources have been unfairly constrained. The term is consequently both technical and expressive: it can describe a precise engineering condition while also conveying frustration at limits imposed on growth, communication, or freedom of movement.

Where does throttled come from?
“Throttled” comes from the Middle English verb throttle, which originally meant to choke or strangle. The word is related to throat, and its mechanical senses developed by analogy with restricting the flow of air or other material. The past tense and past participle came to function independently as an adjective before the action, as in “the throttled engine.”
How throttled is actually used
