verb
ruminate
ROO-muh-nayt/ˈruːmɪneɪt/
To chew food returned from the stomach.
The cows rest in the shade and ruminate after grazing.

Etymology
The “gullet” root led to a verb meaning “chew the cud,” which Latin also used for turning something over in the mind. Mental rumination treats a thought like food returned for repeated chewing.
In context
the drive to ruminate often subsides when we find some way to get our thoughts out of our heads where they just go in circles and give them some external expression.
