Distribute Remain flyers on a regular basis (6)
I believe the answer is:
airmen
'flyers on a regular basis' is the definition.
'airmen' can be an answer for 'flyers' ('airman' can be a synonym of 'flyer'). I'm not sure about the 'on a regular basis' bit.
'distribute remain' is the wordplay.
'distribute' indicates anagramming the letters (I've seen this in other clues).
'remain' with letters rearranged gives 'AIRMEN'.
Can you help me to learn more?
(Other definitions for airmen that I've seen before include "members of the armed forces?" , "Flyers" , "Some engaged in 7 [NATIONAL SERVICE]" , "Marine (anag)" , "Male aviators" .)
