The top bar is in the wrong place (8)
I believe the answer is:
pinnacle
'the top' is the definition.
(pinnacle is a kind of top)
'bar is in the wrong place' is the wordplay.
'bar' becomes 'inn' (I've seen this before**).
'is in' indicates putting letters inside.
'the wrong' is an anagram indicator.
'place' is an anagram of 'pacle'.
'inn' inserted within 'pacle' is 'PINNACLE'.
(Other definitions for pinnacle that I've seen before include "High pointed piece of rock" , "Apogee" , "The highest point, peak" , "Crown" , "Apex" .)
