A flair for keeping almost all in temporary accommodation (6)
I believe the answer is:
talent
'a flair' is the definition.
(I've seen this before)
'almost all in temporary accommodation' is the wordplay.
'almost' means to remove the last letter (most of the word but not all of it).
'in' indicates putting letters inside.
'temporary accommodation' becomes 'tent' (people stay in a tent temporarily).
'all' with its last letter taken away is 'al'.
'al' inserted into 'tent' is 'TALENT'.
'for keeping' is the link.
I am not very happy about this link. Some or all of it may belong to another bit of the clue.
Can you help me to learn more?
(Other definitions for talent that I've seen before include "Natural ability or aptitude" , "Genius" , "Natural ability or gift" , "Natural endowment" , "Special aptitude for the old Greek money" .)
