Over bog, backside of addict gets injected many times (5)
I believe the answer is:
often
'many times' is the definition.
(synonyms)
'over bog backside of addict gets' is the wordplay.
'over' becomes 'o' (cricket abbreviation).
'bog' becomes 'fen' (I've seen this in another clue).
'backside of' suggests the final letters.
'gets' is an insertion indicator.
The last letter of 'addict' is 't'.
'fen' going around 't' is 'ften'.
'o'+'ften'='OFTEN'
'injected' is the link.
This may not be correct. It may belong to another bit of the clue.
Can you help me to learn more?
(Other definitions for often that I've seen before include "Repeatedly, many times" , "Frequently, many times" , "Commonly" , "Regularly" , "In many cases" .)
