Growing evidence that I'm within call, perhaps (5)
I believe the answer is:
lilac
'growing evidence' is the definition.
Both the answer and definition are adjectives. Perhaps you can see a link between them that I don't see?
'i'm within call perhaps' is the wordplay.
'i'm' becomes 'i' (I've seen this in other clues).
'within' is an insertion indicator.
'perhaps' is an anagram indicator.
'call' is an anagram of 'llac'.
'i' placed inside 'llac' is 'LILAC'.
'that' acts as a link.
Can you help me to learn more?
(Other definitions for lilac that I've seen before include "Fragrant, pale purple flower" , "Pale mauve colour for a flower" , "garden ornamental" , "Light purple - shrub" , "Flower celebrated by Schubert" .)
