* The Relationship: The blindfold covers and blocks the eyes, preventing them from seeing.
* Looking for: We want something that covers and blocks the mouth, preventing it from doing its primary function.
Here are some possible analogies, each with a slightly different emphasis:
* Gag to mouth: A gag is specifically designed to silence someone by blocking their mouth.
* Tape to mouth: Similar to a gag, tape can be used to seal the mouth shut, preventing speaking.
* Mask to mouth: While a mask doesn't completely block the mouth, it significantly hinders its function by covering it and forcing breathing through a restricted space.
* Hand to mouth: A hand covering the mouth can temporarily silence someone, though it's not as effective as a physical barrier.
The best analogy depends on the context and the specific meaning you want to convey.
