Disgusted utterance of a hot-headed bachelor (3)
I believe the answer is:
bah
'disgusted utterance of a' is the definition.
I can't judge whether this definition defines the answer.
'hot-headed bachelor' is the wordplay.
I cannot really see how this works, but
'hot' could be 'h' (abbreviation eg on taps) and 'h' is found within the answer.
'bachelor' could be 'ba' (the qualification: Bachelor of Arts) and 'ba' is present in the answer.
No letters remain.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for bah that I've seen before include "Appalling!" , "Exclamation of disgust or annoyance" , "Expression of disgust or contempt" , "Exclamation of contempt or disgust - Scrooge used to say it" , "Comic expression of contempt" .)
