Page starts eating spinach after her skin infection (6)
I believe the answer is:
herpes
'skin infection' is the definition.
'herpes' can be an answer for 'skin' (thesaurus). I am not certain of the 'infection' bit.
'page starts eating spinach after her' is the wordplay.
'page' becomes 'p'.
'starts' suggests taking the first letters.
'after' says to put letters next to each other.
The initial letters of 'eating spinach' is 'es'.
'p'+'es'='pes'
'pes' after 'her' is 'HERPES'.
Can you help me to learn more?
(Other definitions for herpes that I've seen before include "15 across (anag)" , "Skin disease - shingles, for instance" , "Viral disease of the skin" , "Virus disease causing blisters on skin" , "Sphere of virus disease" .)
