provenance -PRO-ven-AHNS - the source or origin of something
Example: "While the sources of our commercial films are hardly original, those from foreign film makers are of unusual provenance."
As a starter: and as a former teacher in English, I hope to add to reader's vocabulary by presenting a word a day in simple terms that anyone can understand - from current use in publications, radio,TV, etc. Remember: use a new word three times in a day and it's yours forever!
