Woods perhaps line outside of garden's entrance (5)
I believe the answer is:
tiger
'woods' is the definition.
Although both the answer and definition are singular nouns, I can't understand how one could define the other.
'line outside of garden's entrance' is the wordplay.
'line' becomes 'tier' (tier is a kind of line).
'outside of' indicates putting letters inside.
'entrance' indicates taking the first letters.
The initial letter of 'gardens' is 'g'.
'tier' going around 'g' is 'TIGER'.
'perhaps' acts as a link.
Can you help me to learn more?
(Other definitions for tiger that I've seen before include "Fierce Bengal beast" , "Big cat of Asia" , "Dynamic type - striped animal" , "Large striped cat" , "Ferocious person" .)
