Part of safari sent up (5)
I believe the answer is:
risen
'up' is the definition.
(similar in meaning)
'part of safari sent' is the wordplay.
'part of' indicates the answer is hidden within the clue.
'RISEN' is hidden within 'safari sent'.
(Other definitions for risen that I've seen before include "Got up" , "Resin (anag.)" , "Suggestive of soil" , "stirred" , "Gone up" .)
