A place to see pigeons flying (5)
I believe the answer is:
aloft
'pigeons flying' is the definition.
'aloft' can be an answer for 'flying' (I've seen this in another clue). I'm not sure about the 'pigeons' bit.
'a place to see' is the wordplay.
'place' becomes 'ft' (I can't explain this - if you can you should believe this answer much more).
'to' says to put letters next to each other (I've seen this in other clues).
'see' becomes 'lo' ('lo' is an archaic exclamation meaning 'look!').
'ft' put after 'lo' is 'loft'.
'a'+'loft'='ALOFT'
Can you help me to learn more?
(Other definitions for aloft that I've seen before include "In the air, overhead" , "as 1 ac [PEGASUS] was?" , "Heading for heaven" , "in a high position" , "at high altitude" .)
