Good sort of simple spot (7)
I believe the answer is:
glimpse
'spot' is the definition.
(I've seen this before)
'good sort of simple' is the wordplay.
'good' becomes 'g' (abbreviation).
'sort of' is an anagram indicator.
'simple' is an anagram of 'limpse'.
'g'+'limpse'='GLIMPSE'
(Other definitions for glimpse that I've seen before include "Catch brief sight of" , "Just a fleeting sighting" , "Momentary view (of something)" , "Brief look" , "A brief view or sighting" .)
