Pull down one's tents in the country or desert (6)
I believe the answer is:
decamp
'desert' is the definition.
(thesaurus)
'pull down one's tents in the country' is the wordplay.
I cannot really see how this works, but
'down' could be 'd' and 'd' is present in the answer.
'one's' could be 'am' ('one is' can humorously mean 'I am') and 'am' is present in the answer.
This may be the basis of the clue (or it may be nonsense).
'or' is the link.
Can you help me to learn more?
(Other definitions for decamp that I've seen before include "Depart quickly and in secret" , "Fold up tent and depart" , "Depart suddenly or secretly" , "Fold up tents and depart" , "Abscond" .)
