Union action to remove ants from septic tank (6)
I believe the answer is:
picket
'union action' is the definition.
The answer and definition can be both man-made objects as well as being singular nouns.
Perhaps they are linked in a way I don't understand?
'remove ants from septic tank' is the wordplay.
'remove' indicates anagramming the letters (move the letters again).
'from' is a deletion indicator.
'septic'+'tank'='septictank'
'septictank' with 'ants' taken out is 'epictk'.
'epictk' is an anagram of 'PICKET'.
'to' is the link.
Can you help me to learn more?
(Other definitions for picket that I've seen before include "Pale" , "Fence of pointed stakes" , "Wooden stake for a fence" , "Small patrol" , "Protesting striker" .)
