Administered glucose initially... vein is ruptured... (5)
I believe the answer is:
given
'administered' is the definition.
The answer and definition can be both to do with ownership as well as being past participle verbs.
Perhaps there's a link between them I don't understand?
'glucose initially vein is ruptured' is the wordplay.
'initially' says to take the initial letters.
'is ruptured' indicates anagramming the letters.
The first letter of 'glucose' is 'g'.
'vein' with letters rearranged gives 'iven'.
'g'+'iven'='GIVEN'
Can you help me to learn more?
(Other definitions for given that I've seen before include "Lent?" , "Awarded" , "Accepted as true" , "supplied" , "Donated" .)
