Victoria maybe in dishevelled raiment by lake (8)
I believe the answer is:
terminal
'victoria maybe' is the definition.
I can't tell whether this definition defines the answer.
'dishevelled raiment by lake' is the wordplay.
'dishevelled' indicates an anagram.
'by' is a charade indicator (letters next to each other).
'lake' becomes 'L' (geographical abbreviation).
'raiment' is an anagram of 'termina'.
'termina'+'l'='TERMINAL'
'in' acts as a link.
Can you help me to learn more?
(Other definitions for terminal that I've seen before include "Ending in death" , "confirming departure" , "At the end; connection" , "Deathly" , "Situated at the end" .)
