Obedient turn by junction in fluid arrangement (7)
I believe the answer is:
dutiful
'obedient' is the definition.
(similar in meaning)
'turn by junction in fluid arrangement' is the wordplay.
'turn by' becomes 'u' (a 'U-turn' is a kind of turn. I am not sure about the 'by' bit.).
'junction' becomes 't'.
'in' is an insertion indicator.
'arrangement' is an anagram indicator.
'u'+'t'='ut'
'fluid' anagrammed gives 'diful'.
'ut' placed inside 'diful' is 'DUTIFUL'.
Can you help me to learn more?
(Other definitions for dutiful that I've seen before include "to be working properly?" , "Compliant, obedient" , "Attentive to one's obligations" , "Punctilious" , "Conscientious and responsible" .)
