Delete from the incorrect chart the scout is holding (7,3)

Ross

I believe the answer is:

'delete' is the definition.
(thesaurus)

'the incorrect chart the scout is holding' is the wordplay.
'the incorrect' is an anagram indicator.
'is holding' is an insertion indicator.
'chart' anagrammed gives 'ratch'.
'ratch' going within 'scout' is 'SCRATCH OUT'.

'from' is the link.
