Some overseas education, relaxed (5)
I believe the answer is:
eased
'relaxed' is the definition.
(I've seen this before)
'some overseas education' is the wordplay.
'some' indicates a hidden word (some of the parts of the word are used).
'EASED' is hidden within 'overseas education'.
(Other definitions for eased that I've seen before include "Comforted" , "Relaxed" , "Made less difficult, relieved from anxiety" , "Made less hard" , "Made less severe" .)
