Yip, you're right.
I believe the dutch language forms the basis for my native language - afrikaans, but I do not even remember what a geyser (engligh) is called in afrikaans, we've sort of adopted the english term, same as garage (in afrikaans - motorhuis), but very few afrikaans people still use that.
the english also borrowed some words from afrikaans, such as lekker, normaly described when something tastes good, then you would say something like damn this steak is lekker. It has become a bit of a slang term here, e.g. lekker dude, see you tomorrow. Nothing to do with food, see.
etc. etc. etc.
