Ancient Germans' ghost, perhaps (5)
I believe the answer is:
goths
'ancient germans' ghost perhaps' is the definition.
I can't tell whether this definition defines the answer.
'ghost perhaps' is the wordplay.
'perhaps' indicates anagramming the letters.
'ghost' anagrammed gives 'GOTHS'.
Can you help me to learn more?
(Other definitions for goths that I've seen before include "Tribesmen who brought down the Roman empire" , "Ancient Germans who gave their name to a style of architecture" , "Germanic invaders of Roman empire" , "A Teutonic people who invaded the Roman Empire" , "Rome's Germanic invaders" .)
