Small fairy that is producing number one photo? (6)
I believe the answer is:
selfie
'number one photo?' is the definition.
'selfie' can be an answer for 'photo?' (I have seen 'Personal photo' mean 'selfie' so perhaps 'photo' could also mean 'selfie'). I am not certain of the 'number one' bit.
'small fairy that is' is the wordplay.
'small' becomes 's' (abbreviation - e.g. clothes size).
'fairy' becomes 'elf' (elf is a kind of fairy).
'that is' becomes 'ie' (abbreviation for id est, 'that is' in Latin).
's'+'elf'+'ie'='SELFIE'
'producing' is the link.
Can you help me to learn more?
(Other definitions for selfie that I've seen before include "Personal photo" , "21 [PHOTO]" .)
