What volcano may do during another upthrust (5)
I believe the answer is:
erupt
'what volcano may do' is the definition.
The definition suggests a singular noun but the answer is not.
'during another upthrust' is the wordplay.
'during' indicates the answer is hidden within the clue.
'ERUPT' is hidden within 'another upthrust'.
Can you help me to learn more?
(Other definitions for erupt that I've seen before include "Eject lava" , "Burst forth, like 25" , "Break out suddenly and violently" , "suddenly burst out" , "Break forth" .)
