Nigel Plat exported some rubber base? (5)
I believe the answer is:
latex
'rubber base?' is the definition.
'latex' can be an answer for 'rubber' (I have seen 'Liquid rubber ' mean 'latex' so perhaps 'rubber' could also mean 'latex'). I am not certain of the 'base?' bit.
'nigel plat exported some' is the wordplay.
'some' indicates a hidden word.
'LATEX' can be found hidden inside 'nigel plat exported'.
Can you help me to learn more?
(Other definitions for latex that I've seen before include "Tree fluid used to make rubber" , "Milky sap of rubber tree" , "Rubber solution" , "Milky fluid of rubber tree" , "Liquid used in making rubber" .)
