The boards put on rickety gates (5)
I believe the answer is:
stage
'the boards' is the definition.
(I've seen this before)
'rickety gates' is the wordplay.
'rickety' is an anagram indicator.
'gates' anagrammed gives 'STAGE'.
'put on' acts as a link.
This may not be correct. Some or all of it may be part of another bit of the clue.
Can you help me to learn more?
(Other definitions for stage that I've seen before include "Put on (a performance)" , "division" , "horse-drawn vehicle" , "Section of a rocket" , "Put on (play); section of race" .)
