They help with new ideas (5)
I believe the answer is:
aides
'they help' is the definition.
(I've seen this before)
'new ideas' is the wordplay.
'new' indicates an anagram.
'ideas' anagrammed gives 'AIDES'.
'with' acts as a link.
(Other definitions for aides that I've seen before include "Right-hand men" , "Helpers" , "Confidential assistants" , "Helpful officers" , "They help" .)
