The following questions contain a cryptic clue. The word to which the clue points can be found amongst the answer options given. The only catch is that the answer options are scrambled...
Cryptic clues function whereby one part of the clue (a word or phrase at either the beginning or the end of the clue) refers to the word's meaning, while the rest of the clue indicates the structure of the word.
Vehicle first priority is fish.
I don't know
In this case, the answer would be rpac, which unscrambled, gives carp. A car is a substitute for vehicle. The phrase "first priority" indicates that the first letter from the word priority should be used ('p'). In this case, the last word in the clue ('fish') provides the meaning of the word. Thus we have car + p = carp.
