Park officer has right to get people annoyed (6)
I believe the answer is:
ranger
'park officer' is the definition.
(I've seen this before)
'right to get people annoyed' is the wordplay.
I cannot really see how this works, but
'right' could be 'r' (common abbreviation) and 'r' is found within the answer.
The remaining letters 'anger' is a valid word which might be clued in a way I don't see.
This explanation may well be incorrect...
'has' acts as a link.
Can you help me to learn more?
(Other definitions for ranger that I've seen before include "Forest defender" , "Forest official" , "Park warden" , "Forest or park officer" , "Keeper of national park or Texas policeman" .)
