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

'it would make stay' is the definition.
The definition suggests a singular noun which matches the answer.

'with british hosts healthy one' is the wordplay.
'with' becomes 'w' (abbreviation**).
'british' becomes 'b' (abbreviation e.g. in 'BBC').
'hosts' is an insertion indicator.
'healthy' becomes 'hale' ('hale' can be similar in meaning to 'healthy').
'w'+'b'='wb'
'wb' enclosing 'hale' is 'whaleb'.
'whaleb'+'one'='WHALEBONE'
