I __ swear that I am up to no good says Potter

Building material made from cement and water

Carefully choreographed dance sequences

Beatles’ album with line drawings cover

Mediterranean plant with a human-like root

Patch of land for plane landings and take-offs

Tuxedo-dressed avians from the South Pole

A native of Ireland’s capital city

The mysterious Scottish river monster

Aurora __ is also known as the Northern Lights
