Answer:
See below.
Step-by-step explanation:
The author is probably reminding us that knowing the origins of words helps us to remember what they mean.
If "verde" means "green", the "verd" in "verdigris" probably means that verdigris is green.
However, the "verd" in verdigris domes from other languages.
It was originally Latin "viride aeris" (green brass).
In old French it became "verte de Grèce" (green of Greece). The modern French spelling is "vert-de-gris" (green of grey).
The English word "verdigris" comes from the French words.
