Vocabulary lesson from eBay

[rprosperi]

While looking at an item on eBay, I ran across the word "verdigris", which was new to me; I initially assumed it was a typo.

According to Dictionary.com:

verdigris: a green or bluish patina formed on copper, brass, or bronze surfaces exposed to the atmosphere for long periods of time, consisting principally of basic copper sulfate.

So, its clear this word is relevant in the life of most of us, at least most collectors. We've all spent much time cleaning up verdigris from battery spills and age.

I presume this word comes from French (I recognize "verd" - green) - can any French-speaking folks here confirm (or deny) this guess?
