Home in which unopened chest's stuck tight (7)
I believe the answer is:
drunken
'tight' is the definition.
(thesaurus)
I cannot understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for drunken that I've seen before include "Tipsy" , "Inebriated" , "Given to excessive consumption of alcohol" , "Happening during intoxication, under the influence" , "Intoxicated, frequently so" .)
