Seeming over prudent taking temperature (10)
I believe the answer is:
ostensible
'seeming' is the definition.
(I know that seeming can be written as ostensible)
'over prudent taking temperature' is the wordplay.
I cannot quite understand how this works, but
'over' could be 'o' (cricket abbreviation) and 'o' is present in the answer.
'temperature' could be 't' (abbreviation) and 't' is present in the answer.
'prudent' could be 'sensible' (similar in meaning) and 'sensible' is found in the leftover letters.
This accounts for all the letters.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for ostensible that I've seen before include "Professed" , "Manifest" , "Supposed" , "Seeming" , "Apparent" .)
