Cutting vessel, jugular vein's fluid all over the place (9)
I believe the answer is:
universal
'fluid all over the place' is the definition.
I can't judge whether this definition defines the answer.
'cutting vessel jugular vein's' is the wordplay.
I cannot quite understand how this works, but
an anagram of 'vein' is 'nive' which is located in the answer.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for universal that I've seen before include "blanket" , "wide-ranging and comprehensive" , "Applying throughout the world" , "Everywhere applicable" , "Found everywhere" .)
