Something created by senators, say, covering half of Utah (7)
I believe the answer is:
statute
'something created by senators' is the definition.
I can't judge whether this defines the answer.
'say covering half of utah' is the wordplay.
'say' becomes 'state' (synonyms).
'covering' is an insertion indicator.
'half of' means to take half the letters.
'utah' cut in half is 'ut'.
'state' going around 'ut' is 'STATUTE'.
Can you help me to learn more?
(Other definitions for statute that I've seen before include "Set taut (anag.)" , "Law recorded in book" , "Act of law" , "Legislative act" , "Act of Parliament" .)
