Spot model hogging Good Housekeeping's front (5)
I believe the answer is:
sight
'spot' is the definition.
(both can mean to notice or observe)
'model hogging good housekeeping's front' is the wordplay.
'model' becomes 'sit' (e.g. for a painting).
'hogging' means one lot of letters goes inside another.
'front' indicates taking the first letters.
The first letters of 'good housekeepings' is 'gh'.
'sit' enclosing 'gh' is 'SIGHT'.
(Other definitions for sight that I've seen before include "Spot - eyesore" , "Notice" , "something to behold" , "Field of vision" , "Sense" .)
