Royal family associated with Germany originally (4)
I believe the answer is:
king
'royal' is the definition.
(a king is royal)
'family associated with germany originally' is the wordplay.
'family' becomes 'kin' (synonyms).
'associated with' says to put letters next to each other.
'originally' suggests taking the first letters.
The first letter of 'germany' is 'g'.
'kin'+'g'='KING'
(Other definitions for king that I've seen before include "as Solomon was" , "Chess piece" , "Most important chesspiece" , "indispensable on board" , "and 21 Across: Shakespeare play" .)
