Agitated, enraged swordsman's call (2,5)
I believe the answer is:
en garde
'agitated enraged swordsman's call' is the definition.
The answer and definition are not the same part of speech. However, past participle verbs and adjectives sometimes mean the same thing.
'agitated enraged' is the wordplay.
'agitated' indicates an anagram.
'enraged' anagrammed gives 'EN GARDE'.
Can you help me to learn more?
