Some new ideas may be off-target (4)
I believe the answer is:
wide
'off-target' is the definition.
(I've seen this in another clue)
'some new ideas may' is the wordplay.
'some' indicates the answer is hidden within the clue (some parts of the word are used).
'WIDE' is hidden in the letters of 'new ideas may'.
'be' is the link.
(Other definitions for wide that I've seen before include "(At cricket) an extra" , "See 9" , "Extending far" , "Spacious; an extra" , "roomy" .)
