Advanced problem about end of universe (2,4)
I believe the answer is:
hi tech
'advanced' is the definition.
Both the answer and definition are adjectives. Maybe they are linked in a way I don't understand?
'problem about end of universe' is the wordplay.
'problem' becomes 'hitch' (I've seen this before).
'about' means one lot of letters goes inside another.
'end of' suggests the final letters.
The last letter of 'universe' is 'e'.
'hitch' placed around 'e' is 'HI-TECH'.
Can you help me to learn more?
(Other definitions for hi tech that I've seen before include "Extremely modern" , "Sophisticated electronics" , "industrial design" , "style of interior design" , "Making use of up-to-date resources" .)
