Etymology

Origin of ruminate

First recorded in 1525–35; from Latin rūminātus (past participle of rūminārī, rūmināre “to ruminate”), equivalent to rūmin- (stem of rūmen “throat, gullet”; see rumen) + -ātus past participle suffix ( see -ate 1)

Explanation

When you ruminate, it means you are thinking very deeply about something. You're likely to be so lost in thought that you stare off into space and don't hear people when they call your name. Another meaning of ruminate is to "chew the cud," which can mean "to turn it over and over in your mind." Or, if you're a cow, to turn food over and over in your stomachs in order to digest it. Whether you're a human or a cow, if you ruminate, it will take a LONG time.
