Lost one's temper with a guard (6)
I believe the answer is:
railed
'lost one's temper' is the definition.
Although both the answer and definition are past participle verbs, I don't understand how they can define each other.
'a guard' is the wordplay.
I cannot quite understand how this works, but
'a' is present in the answer.
The remaining letters 'riled' is a valid word which might be clued in a way I don't understand.
This may be the basis of the clue (or it may be nonsense).
'with' is the link.
Can you help me to learn more?
(Other definitions for railed that I've seen before include "Complained or protested strongly" , "Complained strongly, being fenced in" , "Complained loudly,being barred" , "Redial (anag.)" , "Protested strongly, being barred" .)
