Regular as new bread (5)
I believe the answer is:
daily
This might be a double definition.
'regular' is the first definition.
(similar in meaning)
'new bread' is the second definition.
'daily' can be an answer for 'bread' (thesaurus). I'm unsure of the 'new' bit.
'as' acts as a link.
Can you help me to learn more?
(Other definitions for daily that I've seen before include "often" , "Cleaner; every 24 hours" , "paper, of a sort" , "regularly" , "Newspaper; cleaner" .)
