Found after eruption from father in Clare (7)
I believe the answer is:
caldera
This clue might be a double definition.
'found after eruption' is the first definition.
The definition suggests a singular noun which matches the answer.
'father in clare' is the second definition.
The definition suggests a singular noun which matches the answer.
'from' acts as a link.
Can you help me to learn more?
