Shrink gets right in touch (8)
I believe the answer is:
contract
'shrink' is the definition.
(I know that shrink can be written as contract)
'gets right in touch' is the wordplay.
'gets right' becomes 'r' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'in' is an insertion indicator.
'touch' becomes 'contact' (contact is a kind of touch).
'r' inserted within 'contact' is 'CONTRACT'.
Can you help me to learn more?
(Other definitions for contract that I've seen before include "type of bridge" , "Undertake" , "Become smaller" , "Agreement - lessen" , "bargain" .)
