At any cost I organised a kind of holiday (10)
I believe the answer is:
staycation
'a kind of holiday' is the definition.
'staycation' can be an answer for 'holiday' (I have seen 'local holiday' mean 'staycation' so perhaps 'holiday' could also mean 'staycation'). I am not sure about the 'a kind of' bit.
'at any cost i organised' is the wordplay.
'organised' indicates an anagram.
'at'+'any'+'cost'+'i'='atanycosti'
'atanycosti' is an anagram of 'STAYCATION'.
Can you help me to learn more?
(Other definitions for staycation that I've seen before include "Holiday at home" , "local holiday" .)
