neither apples nor pine are in pineapple
The fruit looks like pine cones. Back in that day pine cones were called pineapples, thus the fruit was called a pineapple.
Also
a guinea pig is neither from Guinea nor a pig
I know that the pig part comes from the fact that they are able to produce piglike sounds. Don`t know where the guinea comes from (but you can probably google it and find out)
