One way to get sick is to booze (5)

Ross

I believe the answer is:

swill

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

'is to booze' is the definition.
(thesaurus)

'one way to get sick' is the wordplay.
'one way to get' becomes 'sw' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'sick' becomes 'ill' (synonyms).
'sw'+'ill'='SWILL'

Can you help me to learn more?

(Other definitions for swill that I've seen before include "Hogwash" , "Rinse - pig food" , "Wet pig feed" , "drink heavily" , "Refuse" .)
