In university, English Literature's flipping pointless (7)

I believe the answer is:

inutile

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

'pointless' is the definition.
Both the definition and answer are adjectives. Maybe you can see an association between them that I can't see?

'in university english literature's flipping' is the wordplay.
'university' becomes 'u'.
'english' becomes 'e' (abbreviation).
'literature' becomes 'lit'.
'flipping' says the letters should be written backwards.
'e'+'lit'='elit'
'elit' back-to-front is 'tile'.
'in'+'u'+'tile'='INUTILE'

Can you help me to learn more?

(Another definition for inutile that I've seen is " Not worth using, useless".)

I've seen this clue in The Guardian.
