Philosophical German soldier supporting King (4)
I believe the answer is:
kant
'philosophical german' is the definition.
The definition and answer can be both people as well as being singular nouns.
Maybe you can see an association between them that I can't see?
'soldier supporting king' is the wordplay.
'soldier' becomes 'ant' (soldier ant is a type of ant).
'supporting' is a charade indicator (letters next to each other) (in a down clue, some letters go below others).
'king' becomes 'k' (abbreviation for king in chess).
'ant' after 'k' is 'KANT'.
Can you help me to learn more?
(Other definitions for kant that I've seen before include "Immanuel --, German philosopher" , "Idealist" .)
