Tea at home, or one of the many restaurants? (5)
I believe the answer is:
chain
'one of the many restaurants?' is the definition.
The answer and definition can be both quantities as well as being singular nouns.
Maybe you can see an association between them that I don't see?
'tea at home' is the wordplay.
'tea' becomes 'cha' (cha is a type of tea).
'at home' becomes 'in' ('I'm in' can mean 'I'm at home').
'cha'+'in'='CHAIN'
'or' is the link.
Can you help me to learn more?
(Other definitions for chain that I've seen before include "A measure" , "unwelcome to house seeker" , "Shackle" , "Handcuff" , "Series of connected links" .)
