No Delft cracks that many times (7)
I believe the answer is:
tenfold
'many times' is the definition.
'tenfold' can be an answer for 'times' (I have seen 'several times' mean 'tenfold' so perhaps 'times' could also mean 'tenfold'). I am not certain of the 'many' bit.
'no delft cracks' is the wordplay.
'cracks' is an anagram indicator (I've seen 'cracked' mean this).
'no'+'delft'='nodelft'
'nodelft' is an anagram of 'TENFOLD'.
'that' is the link.
Can you help me to learn more?
(Other definitions for tenfold that I've seen before include "(Multiplied) by putting 0 on end" , "An order of magnitude as much" , "several times" , "x10" , "(Increased) by an order of magnitude" .)
