Last act of Jesus -- Son, in case uncertain? (9)
I believe the answer is:
ascension
'last act of jesus' is the definition.
The answer and definition can be both related to time as well as being singular nouns.
Perhaps you can see a link between them that I can't see?
'son in case uncertain?' is the wordplay.
'uncertain?' is an anagram indicator (I've seen 'uncertain' mean this).
'son'+'in'+'case'='sonincase'
'sonincase' anagrammed gives 'ASCENSION'.
Can you help me to learn more?
(Other definitions for ascension that I've seen before include "religious feast" , "Canonise on the way up to heaven" , "distance in hours measured by this, right?" , "Canonises on Christ's way to heaven" , "Island in the South Atlantic" .)
