Host feeling up to correcting mistake when speaking (4,2,3,6)
I believe the answer is:
slip of the tongue
'mistake when speaking' is the definition.
I can't tell whether this definition defines the answer.
'host feeling up to correcting' is the wordplay.
'correcting' indicates an anagram (the order of letters must be corrected).
'host'+'feeling'+'up'+'to'='hostfeelingupto'
'hostfeelingupto' with letters rearranged gives 'SLIP OF THE TONGUE'.
Can you help me to learn more?
(Other definitions for slip of the tongue that I've seen before include "a small error" , "Error in words" , "mistake one hears" , "vocal error" .)
