Pressing demand from internet pioneer for friends at university in German city (9)
I believe the answer is:
ultimatum
'pressing demand from internet pioneer' is the definition.
I can't judge whether this definition defines the answer.
'friends at university in german city' is the wordplay.
'friends' becomes 'tim' (I can't justify this - if you can you should believe this answer much more).
'university' becomes 'U' (abbreviation for university).
'in' indicates putting letters inside.
'german city' becomes 'ulm' (Ulm is a city in Germany).
'tim'+'at'+'u'='timatu'
'timatu' put inside 'ulm' is 'ULTIMATUM'.
'for' is the link.
Can you help me to learn more?
(Other definitions for ultimatum that I've seen before include "A final demand - or else" , "Final demand or statement of terms" , "Final statement of actions required of another" , "Final (peremptory) demand" , "Uncompromising demand" .)
