In which one's local confused with home endlessly? (10)

I believe the answer is:

alcoholism

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

'in which one's' is the definition.
Although both the answer and definition are singular nouns, I cannot understand how they can define each other.

'local confused with home endlessly?' is the wordplay.
'confused' indicates anagramming the letters.
'with' means one lot of letters goes inside another.
'home' becomes 'HO' (abbreviation for house).
'endlessly?' becomes 'ism' (I am not sure about this - if you are sure you should believe this answer much more).
'local' is an anagram of 'alcol'.
'alcol' placed around 'ho' is 'alcohol'.
'alcohol'+'ism'='ALCOHOLISM'

Can you help me to learn more?

(Other definitions for alcoholism that I've seen before include "Drink problem" , "Addiction to drink" .)
