Take the first left turn at the zoo (4)
I believe the answer is:
lion
'take' is the definition.
Although both the answer and definition are singular nouns, I cannot understand how one could define the other.
'first left turn at the zoo' is the wordplay.
I cannot quite see how this works, but
'first' could be 'i' (Roman numeral for one or first) and 'i' is found in the answer.
'left' could be 'l' (common abbreviation) and 'l' is present in the answer.
'at' could be 'on' (location) and 'on' is located in the answer.
This accounts for all the letters.
This explanation may well be incorrect...
'the' acts as a link.
Can you help me to learn more?
(Other definitions for lion that I've seen before include "King of the forest" , "Buddhist scripture; Sanskrit rule" , "Important figure" , "Cowardly visitor in Oz" , "Simba, for example" .)
