*oak* I like the way my mouth feels when I say it, it rounds out, with a solid "K" at the end of the word, almost like thumping on a good solid piece of oak furniture.
also, 2 non-english words which I will probably misspell; "hubschrauber" which is german for helicopter, my kids and I used to hold our arms out and spin in circles going "hub-hub-hub" which kind of sounds like helicopter sounds.
"regenschirm" which is german for umbrella, it feels like the regen (rain) has been schirmed away
