Each clue relates to the eight-letter word as well as the two four-letter words. Combine a word from the left column with one from the right.
e.g. 'Rotate a freshwater fish while at a toll gate' would lead to 'turn' (rotate) and 'pike' (freshwater fish) which, when combined, form 'turnpike' (toll gate). Note: clues are not always in this order.
