Source, for example, rejected by Press Association reveals what can be seen at theguardian.com? (4,4)
I believe the answer is:
home page
'what can be seen at theguardian com?' is the definition.
I can't tell whether this definition defines the answer.
'source for example rejected by press association' is the wordplay.
'source' becomes 'home' (home is a kind of source).
'for example' becomes 'e.g.' (short for 'exempli gratia', 'for example' in Latin).
'rejected' shows that the letters should be reversed in order.
'by' says to put letters next to each other.
'press association' becomes 'PA' (abbreviation for Press Association).
'eg' written backwards gives 'ge'.
'ge' after 'pa' is 'page'.
'home'+'page'='HOME PAGE'
'reveals' is the link.
Can you help me to learn more?
(Other definitions for home page that I've seen before include "website feature" , "First part of site" , "on-screen introduction" , "First point of call on website" , "Website domain?" .)
