Your English teacher is as mad as a fish.
Yorkshire dialect = north of England (Sean Bean as Boromir or Ned Stark). Found in Wuthering Heights/The Secret Garden.
Moorish dialect = well... The Moors were medieval Muslims from North Africa who conquered much of southern Europe 1300 years ago. To say something is 'Moorish' means you are pertaining to their culture. They influenced the Basque (now a region of France and Spain) language heavily, so if there was a 'Moorish dialect' of anything it would be of Basque (does sound a bit like 'Baroque', admittedly

).
Nothing Moorish in Wuthering Heights!
I guess I was lucky in that I was familiar enough with Yorkshire that I didn't notice it in Wuthering Heights or The Secret Garden! lol
I think I'm off-topic, sorry!
