Learn English – visual equivalent of the word “overhear”

The word phenomime can be used for words that act like onomatopoeia (also known as phonomimes) for non-auditory sensory stimuli (the other four senses). They are quite common in Japanese, which also has psychomimes (words that act like onomatopoeia for emotions, thought processes, states of mind).

• Phonomimes use word sounds to represent auditory stimuli, such as a bark, a meow, or a honk.
• Phenomimes use word sounds to represent non-auditory stimuli, such as a flash, a twinkle, or a grope.
• Psychomimes use word sounds to represent psychological stimuli, such as the pitter-pat of a quickened heart, dizziness, or reluctance.

EDIT
I removed my reference to a Wikipedia article that used the term compressive asphyxia. It appears that the article may be corrupted. I'm no longer sure how widespread that particular term is.
