'thinner' is the definition.
Both the answer and definition are comparative adjectives. Maybe there's an association between them I don't understand?

'forest officer stretched by one' is the wordplay.
I cannot really see how this works, but
'one' could be 'an' (an apple is one apple) and 'an' is found in the answer.
This may be the basis of the clue (or it may be nonsense).
