They may unintentionally reveal sinful despair somehow (8,5)

I believe the answer is:

freudian slips

I'm a little stuck... Click here to teach me more about this clue!

'they may unintentionally' is the definition.
I know nothing about this answer so I can't tell whether this works.

'sinful despair somehow' is the wordplay.
'somehow' indicates an anagram.
'sinful'+'despair'='sinfuldespair'
'sinfuldespair' with letters rearranged gives 'FREUDIAN SLIPS'.

'reveal' acts as a link.

Can you help me to learn more?

(Another definition for freudian slips that I've seen is " Errors betraying unconscious thoughts".)

I've seen this clue in The Times.
