Mark has an appealing dialect (5,6)

Ross

I believe the answer is:

acute accent

'mark' is the definition.
(acute accent is a kind of mark)

'an appealing dialect' is the wordplay.
'an' becomes 'a'.
'appealing' becomes 'cute' (I've seen this before).
'dialect' becomes 'accent' (synonyms).
'a'+'cute'+'accent'='ACUTE ACCENT'

'has' is the link.

(Another definition for acute accent that I've seen is " This vowel adjustment".)

I've seen this clue in The Mirror.
