Set my clues lacking any regular form (5)

Ross

I believe the answer is:

style

'form' is the definition.
(style is a kind of form)

'set my clues lacking any regular' is the wordplay.
'lacking any regular' means one should take alternating letters (letters removed at regular intervals).
'set'+'my'+'clues'='setmyclues'
The alternating letters of 'setmyclues' are 'STYLE'.

(Other definitions for style that I've seen before include "Particular kind, of fashion say" , "name" , "term" , "way of writing" , "approach?" .)

I've seen this clue in The Telegraph.
