Old German's attempt to interrupt call by hospital (8)
I believe the answer is:
visigoth
'old german's attempt to interrupt call by hospital' is the definition.
I can't judge whether this definition defines the answer.
'attempt to interrupt call by hospital' is the wordplay.
'attempt' becomes 'go' (go is a kind of attempt).
'to interrupt' indicates putting letters inside.
'call by' becomes 'visit' (synonyms. I am not sure about the 'by' bit.).
'hospital' becomes 'h' (abbreviation for hospital on maps).
'go' placed within 'visit' is 'visigot'.
'visigot'+'h'='VISIGOTH'
Can you help me to learn more?
(Other definitions for visigoth that I've seen before include "One of those who sacked Rome in 410" , "Old European" , "Spanish settler" , "Alaric, eg, who conquered Rome" , "Roman Empire invader" .)
