Dispenser of alcohol has raised tense issue (5)
I believe the answer is:
topic
'issue' is the definition.
('topic' can be a synonym of 'issue')
'dispenser of alcohol has raised tense' is the wordplay.
I cannot quite understand how this works, but
'of' could be 'o' and 'o' is found in the answer.
'tense' could be 't' (abbreviation used in many dictionaries) and 't' is present in the answer.
The remaining letters 'pic' is a valid word which might be clued in a way I don't understand.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for topic that I've seen before include "Subject matter, theme" , "Content of argument" , "A subject for conversation or debate" , "one discussed" , "Subject (eg, of text)" .)
