Give one the right to name a film for example (7)
I believe the answer is:
entitle
'give' is the definition.
The answer and definition can be both to do with communicating as well as being verbs in their base form.
Maybe you can see an association between them that I can't see?
'one the right to name a film for example' is the wordplay.
'the right' indicates one should take the final letters (the letter on the right of the word).
'to name' becomes 'n' (common abbreviation e.g. on forms).
'a film for example' becomes 'title' (I can't explain this - if you can you should give a lot more credence to this answer).
The final letter of 'one' is 'e'.
'e'+'n'+'title'='ENTITLE'
Can you help me to learn more?
(Other definitions for entitle that I've seen before include "Give (someone) rights" , "Name; empower" , "confer rank" , "Warrant" , "Licence" .)
