Send parent travelling by river (9)
I believe the answer is:
enrapture
'send' is the definition.
(thesaurus)
'parent travelling by river' is the wordplay.
'travelling' indicates an anagram.
'by' is a charade indicator (letters next to each other).
'river' becomes 'ure' (I have seen 'River of Wensleydale ' mean 'ure' so perhaps 'river' could also mean 'ure'**).
'parent' is an anagram of 'enrapt'.
'enrapt'+'ure'='ENRAPTURE'
(Other definitions for enrapture that I've seen before include "Ape Turner (anag.)" , "Bewitch" , "Transport" , "Give delight to" , "entrance" .)
