Also fulminated about returning space crafts (4)
I believe the answer is:
ufos
'space crafts' is the definition.
The definition and answer can be both related to thinking as well as being plural nouns.
Maybe they are linked in a way I don't understand?
'also fulminated about returning' is the wordplay.
'about' says the answer is hidden in the clue (the clue goes around or about the answer).
'returning' shows that the letters should be reversed in order.
'sofu' can be found hidden inside 'also fulminated'.
'sofu' in reverse letter order is 'UFOS'.
Can you help me to learn more?
(Other definitions for ufos that I've seen before include "Mysterious objects in sky" , "Potential alien craft" , "Initially, formal flying saucers" , "Unauthorised traffic from outer space?" , "Strange aerial objects" .)
