Give alcohol to legendary director taking clothes off behind screens (9)
I believe the answer is:
lubricate
'give' is the definition.
The definition and answer can be both related to change as well as being verbs in their base form.
Perhaps you can see a link between them that I don't see?
I cannot understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for lubricate that I've seen before include "Oil (a mechanism)" , "supply with booze" , "Coat with oil to reduce friction" , "Bribe" , "Apply oil or grease to" .)
