• assay •
Pronunciation: æ-say • Hear it!
Part of Speech: Verb
Meaning: 1. To determine the content and quality (of ore) or that of a biochemical substance. 2. To assess the nature of something, to evaluate it.

In Play: The California gold rush of 1848-1855 was financial gold rush for assayers, called on to verify a nugget was gold and the quality of the gold. However, we may assay things other than gold: "Herby is a salesman nonpareil who can assay a customer's potential in the blink of an eye."
Word History: This word was taken from Anglo-French assai, which came ultimately from Late Latin exagium "a weighing". Latin exagium is a derivation from the verb exigere "to drive out; examine, try, test", based on ex "out (from)" + agere "to move, drive, lead; do". Its past participle, actus, went into the making of Englihs act, action, and actor. The present participle, agen(t)s, is the basis for English agent. Agere comes from the PIE root ag- "to drive, draw out or forth, move". It may also be component of PIE agro- "field". If so, it went into the making of Greek agros "field" and Latin ager "field, property", which underlies German Acker "field, farmland, the English borrowings acre and agriculture.
