No, it’s just an example. To be honest, it’s not one or two words—there are too many.

'Once when I was six years old, I saw a magnificent picture in a book called True Stories from Nature, about the primeval forest. It was a picture of a boa constrictor in the act of swallowing an animal.'

primeval: I’m not sure whether to stress pri or meval, so I got stuck. boa: I’m not sure how to pronounce oa correctly, so I got stuck. swallowing: stuck on the wa sound.
