With bathroom unfortunately in use, heads for the exit (2,5)
I believe the answer is:
en suite
'with bathroom unfortunately in use heads for the exit' is the definition.
I can't tell whether this definition defines the answer.
'unfortunately in use heads for the exit' is the wordplay.
'unfortunately' is an anagram indicator (a bad or unfortunate spelling).
'heads for' suggests taking the first letters.
The initial letters of 'the exit' is 'te'.
'in'+'use'='inuse'
'inuse' anagrammed gives 'ensui'.
'ensui'+'te'='EN SUITE'
Can you help me to learn more?
(Other definitions for en suite that I've seen before include "(Of bathroom) accessible from the bedroom" , "(Of bathroom) connected to the bedroom" , "Forming a unit or set" , "Forming a single unit, like bedroom and bathroom" , "Forming a 22 dn" .)
