Miss Jamaica oddly ignored important religious figure (5)
I believe the answer is:
isaac
'important religious figure' is the definition.
'isaac' can be an answer for 'figure' (I have seen 'biblical figure' mean 'isaac' so perhaps 'figure' could also mean 'isaac'). I'm not sure about the 'important religious' bit.
'miss jamaica oddly ignored' is the wordplay.
'oddly ignored' indicates alternate letters (letters in odd-numbered positions removed).
'miss'+'jamaica'='missjamaica'
The alternating letters of 'missjamaica' are 'ISAAC'.
Can you help me to learn more?
(Other definitions for isaac that I've seen before include "Jacob's father" , "-- Asimov, science fiction writer" , "Sacrificial offering" , "Sir -- Newton, English scientist" , "Man's name" .)
