I believe the answer is:

pressurise

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

'force' is the definition.
I don't know anything about this answer so I can't tell whether this works.

'purse's tight increase' is the wordplay.
'tight' indicates an anagram (tight can mean drunk).
'increase' becomes 'rise' (rising is a kind of increasing).
'purses' is an anagram of 'pressu'.
'pressu'+'rise'='PRESSURISE'

Can you help me to learn more?

(Another definition for pressurise that I've seen is " Attempt to coerce (into doing something)".)

I've seen this clue in The Telegraph.
