Etymology

Origin of rumination

First recorded in 1580–90; from Latin stem of rūminātiō “a chewing of the cud,” equivalent to rūmināt(us) “chewed over again” (stem of rūmināre; see ruminate ( def. )) + -iō -ion ( def. )

Explanation

If someone asks you to make a difficult decision — like what to have for dinner — it might lead to rumination, or a long period of deep thought. Use the noun rumination when there's thoughtful consideration going on. If your grandfather answers every question by saying, "Hmm. Let me think about that," he is a fan of rumination. It comes from the verb ruminate, which means "to think deeply," but also means "to chew the cud." Both words come from the Latin word ruminatus, which has the same meaning and which is rooted in rumen, or "gullet."
