One wearing a special suit in the bar? (6)
I believe the answer is:
bather
'one wearing a special suit' is the definition.
The answer is a person as well as being a singular noun. This is suggested by the definition.
'the bar?' is the wordplay.
'the bar' anagrams to 'BATHER'.
However, I am not clear how the anagram is indicated.
'in' is the link.
Can you help me to learn more?
(Other definitions for bather that I've seen before include "man getting soaked?" , "one getting into the drink" , "Seaside swimmer" , "One dipping in the briny?" .)
