A seed may be moved carefully (5)
I believe the answer is:
eased
'moved carefully' is the definition.
('ease' can be a synonym of 'move carefully')
'a seed may be' is the wordplay.
'may be' is an anagram indicator.
'a'+'seed'='aseed'
'aseed' anagrammed gives 'EASED'.
(Other definitions for eased that I've seen before include "Slowed down" , "Made less difficult, relieved from anxiety" , "Allievated" , "Relieved, mitigated" , "Given relief" .)
