She can turn alarming occasionally (4)
I believe the answer is:
girl
'she' is the definition.
Both the definition and answer are singular nouns.
Perhaps there's an association between them I don't understand?
'turn alarming occasionally' is the wordplay.
'turn' is a reversal indicator.
'occasionally' indicates alternate letters (letters taken at regular intervals or occasions).
The alternating letters of 'alarming' are 'lrig'.
'lrig' backwards is 'GIRL'.
'can' acts as a link.
Can you help me to learn more?
(Other definitions for girl that I've seen before include "Miss" , "Lass" , "Female child" , "Lassie" , "Maid" .)
