Get up about mid-morning and bathe (5)
I believe the answer is:
rinse
'bathe' is the definition.
(thesaurus)
'get up about mid-morning' is the wordplay.
'get up' becomes 'rise' ('rise' can be a synonym of 'get up'**).
'about' is an insertion indicator.
'mid' indicates the central letters.
The middle of 'morning' is 'n'.
'rise' placed around 'n' is 'RINSE'.
'and' is the link.
(Other definitions for rinse that I've seen before include "Run water through" , "Wash lightly without soap" , "Swill out" , "Hair preparation" , "Wash in clean water" .)
