Managed to carry one bucket? (4)
I believe the answer is:
rain
'bucket?' is the definition.
(eg bucketing down means raining)
'managed to carry one' is the wordplay.
'managed' becomes 'ran' (both can mean organised or was in charge of).
'to carry' indicates putting letters inside.
'one' becomes 'i' (Roman numeral).
'ran' going around 'i' is 'RAIN'.
(Other definitions for rain that I've seen before include "Precipitation" , "previous rule?" , "See 12" , "Come down in showers" , "bad weather" .)
