Give wooden performance, losing nothing (5)
I believe the answer is:
endow
'give' is the definition.
(endow can mean to give or bestow)
I cannot understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for endow that I've seen before include "Provide with a permanent income, say a school" , "Establish (university post) by giving funds" , "Give money to" , "Pay to found" , "Give funding to establish (something)" .)
