Ok I sympathise with Mario...because my mother is Brazilian and my father forbade her to teach my brother and portuguese because he wouldn't be able to understand( why he couldn't learn it as well was always beyond me). Anyway, we both grew up only knowing english...thankfully, after living here in Brazil for six years I can now talk with my mother in a language other than english.

The PLUCK YEW thing is really clutching at straws...the word FUCK actually comes from the middle english word (I think this is right) FUCH or somesuch (I'm doing this from memory folks so don't hold it against me) which means to fuse together/to combine.
