Odd to set limits on scope (7)
I believe the answer is:
strange
'odd' is the definition.
(I've seen this before)
'set limits on scope' is the wordplay.
'limits' means to remove the middle letters.
'on' says to put letters next to each other.
'scope' becomes 'range' (synonyms).
'set' with its middle taken out is 'st'.
'st'+'range'='STRANGE'
'to' is the link.
(Other definitions for strange that I've seen before include "Offbeat" , "Singular" , "Odd, not familiar" , "Funny" , "Different" .)
