Setting up dinner support (8)

Ross

I believe the answer is:

underpin

'support' is the definition.
(I know that support can be written as underpin)

'setting up dinner' is the wordplay.
'setting' is an anagram indicator.
'up'+'dinner'='updinner'
'updinner' is an anagram of 'UNDERPIN'.

(Other definitions for underpin that I've seen before include "Prop up with nun pride" , "Support or strengthen from beneath" , "Form the basis for" , "buttress" , "corroborate" .)

I've seen this clue in The Globe and Mail.
