What family does at funeral with second container for ashes (5)
I believe the answer is:
mourn
'what family does at funeral' is the definition.
The definition suggests a comparative adjective but the answer is not.
'with second container for ashes' is the wordplay.
'with' says to put letters next to each other.
'second' becomes 'mo' (both are short periods of time).
'container for ashes' becomes 'urn' (ashes are typically stored in an urn).
'mo'+'urn' is 'MOURN'.
Can you help me to learn more?
(Other definitions for mourn that I've seen before include "Express sadness" , "Show sorrow for loss" , "Show sorrow at death" , "Lament loss" , "Keen" .)
