Open houses near boundless gorge (7)
I believe the answer is:
overeat
'gorge' is the definition.
(I know that gorge can be written as overeat)
'open houses near boundless' is the wordplay.
'open' becomes 'overt' (associated in meaning).
'houses' is an insertion indicator.
'boundless' indicates the central letters (the limits or bounds of the word are removed).
The central letters of 'near' are 'ea'.
'overt' placed around 'ea' is 'OVEREAT'.
(Other definitions for overeat that I've seen before include "Gobble to excess" , "ignore threat of a big corporation?" , "Gorge oneself" , "pig out?" , "Stuff oneself silly" .)
