Credit card company that hasn't opened bank account (3)
I believe the answer is:
isa
'credit card company' is the definition.
I know nothing about this answer so I can't judge whether it can be defined by this definition.
'hasn't opened bank account' is the wordplay.
'hasn't opened' becomes 'i' (I can't justify this - if you can you should believe this answer much more).
'bank' says to hollow out the word (remove centre letters) (I've seen 'banks of' mean this (the banks are the sides of the word)).
'account' becomes 'saga' (I've seen this in another clue).
'saga' with its middle removed is 'sa'.
'i'+'sa'='ISA'
'that' is the link.
Can you help me to learn more?
(Other definitions for isa that I've seen before include "Tax-free savings account" , "Tax-free savings scheme" , "Tax-free investment" , "Individual Savings Account" .)
