noun / verb
fear
FEER/fɪr/
A feeling of alarm or worry about possible danger or harm.
The woman recoils in fear when she sees the snake on the path.

Etymology
Old English fær named the danger itself—a calamity, peril, or sudden attack. The meaning shifted from the threatening event to the uneasy emotional state caused by possible danger.
In context
This response starts with the amygdala, the brain region involved in processing fear. When the amygdala perceives danger, it stimulates the sympathetic nervous system, which triggers the release of adrenaline.
