Saw fit to have cold water in the garden (5)
I believe the answer is:
chose
'saw fit' is the definition.
('choose' can be a synonym of 'see fit')
'cold water in the garden' is the wordplay.
I cannot really understand how this works, but
'cold' could be 'c' (eg on taps) and 'c' is found in the answer.
'water' could be 'hose' (water a flowerbed say) and 'hose' is located in the answer.
This accounts for all the letters.
This may be the basis of clue (or it may be nonsense).
'to have' is the link.
Can you help me to learn more?
(Other definitions for chose that I've seen before include "item from Paris" , "Selected" , "Picked" , "article from Paris" , "Determined" .)
