Often visit common (8)
I believe the answer is:
frequent
I believe this clue is a triple definition!
'often' is the first definition.
(I've seen this before)
'visit' is the second definition.
(I've seen this before)
'common' is the third definition.
('frequent' can be similar in meaning to 'common')
(Other definitions for frequent that I've seen before include "Common" , "Occurring many times at short intervals" , "Occurring often" , "Often, habitual" , "happening regularly at short intervals" .)
