Crossword Genius

What could shock more or less, for example? (4-6,4)

Ross

I believe the answer is:

four-letter word

This clue is a double definition.

'what could shock' is the first definition.
(a four-letter swear word could shock people)

'more or less for example?' is the second definition.
('more' and 'less' have 4 letters each)

(Another definition for four-letter word that I've seen is " profanity".)

I've seen this clue in The Times.
