Sun worshipper perhaps again leaving India, under pressure (5)
I believe the answer is:
pagan
'sun worshipper' is the definition.
The definition and answer can be both people as well as being singular nouns.
Perhaps you can see a link between them that I can't see?
'again leaving india under pressure' is the wordplay.
'leaving' is a deletion indicator.
'india' becomes 'i' (phonetic alphabet: alpha, bravo, charlie etc.).
'under' says to put letters next to each other (in a down clue, some letters go below others).
'pressure' becomes 'p' (abbreviation).
'again' with 'i' taken away is 'agan'.
'agan' put after 'p' is 'PAGAN'.
'perhaps' acts as a link.
Can you help me to learn more?
(Other definitions for pagan that I've seen before include "Not conventionally religious" , "A heathen, not a Christian" , "Unchristian" , "Heathen; non-believer" , "One outside the main religions" .)
