Did you know?

Consummate is a consummate example of a word that’s shifted in meaning over the centuries. A 15th century addition to the language ultimately from Latin consummare, meaning “to sum up, finish,” the word first described something that has been brought to completion. Shakespeare used the word this way in Measure for Measure: “Do you the office, friar; which consummate, Return him here again.” By the early 16th century consummate had taken on the meaning of “complete in every detail.” Today it usually describes someone or something extremely skilled and accomplished, but it can also describe that which is supremely excellent, as well as that which is simply extreme.
