'german' is the definition.
The answer and definition are different parts of speech. However, adjectives and past participle verbs can sometimes define each other.

'bomb planted dropped in' is the wordplay.
'bomb' becomes 'vi' (the V-s was a world war II flying bomb).
'planted dropped in' becomes 'sited' (I am not sure about this - if you are sure you should believe this answer much more).
'vi'+'sited'='VISITED'

Can you help me to learn more?

(Other definitions for visited that I've seen before include "Went to see" , "Looked up" , "came to see" , "Saw" , "Called in (5)" .)
