copper, Cyprus, cypress and gopher

Sometimes it feels like tracking the etymologies of words is like a centuries long game of telephone. Let me show you what I mean.

Here's the Online Etymology Dictionary for the word "copper":

late Old English coper, from Proto-Germanic *kupar (source also of Middle Dutch koper, Old Norse koparr, Old High German kupfar), from Late Latin cuprum, contraction of Latin Cyprium (aes) "Cyprian (metal)," after Greek Kyprios "Cyprus"

So copper comes from Cyprus (both linguistically and physically). Where does the name Cyprus come from?

large eastern Mediterranean island, late 14c., Cipre, Cipres, from Latinized form of Greek Kypros "land of cypress trees"

Cyprus/cypress. Fair enough. So what is the etymology of cypress? Here we get to a Hebrew connection:

from Old French cipres (12c., Modern French cyprès), from Late Latin cypressus, from Latin cupressus, from Greek kyparissos, probably from an unknown pre-Greek Mediterranean language. Perhaps it is related to Hebrew gopher, name of the tree whose wood was used to make the ark (Genesis vi.14).

Here we probably have arrived at almost the end of the line. Klein doesn't have much to offer as to the origin of gofer גפר:

m.n. ‘gopher’ (a kind of wood of which Noah’s ark was made). [Of unknown origin. Perhaps related to Akka. giparu.]

Sarna, in his JPS commentary on the one appearance of gofer (Bereshit 6:14), writes:

Many modern scholars prefer the cypress both because of a similarity in sound to the Hebrew and because it was widely used in shipbuilding in ancient times, due to its resistance to rot.

Giparu meant a kind of reed in Akkadian. It's unclear to me how a word for a reed became the word for a tree - unless both were used to build boats (compare the ark of Noah to the ark of baby Moses.) But I guess that's the nature of telephone - the further you go along, the harder it is to figure out what the original message was...
