Trial in US city making the news (6)
I believe the answer is:
latest
'news' is the definition.
(the latest means the latest news)
'trial in us city making' is the wordplay.
I cannot quite see how this works, but
'trial' could be 'test' (synonyms) and 'test' is found in the answer.
'city' could be 'la' (Los Angeles) and 'la' is found within the answer.
No letters remain.
This explanation may well be incorrect...
'the' acts as a link.
Can you help me to learn more?
(Other definitions for latest that I've seen before include "style of today" , "Most up to the minute" , "Most recent or most unpunctual" , "hot bit of news" , "Most up-to-date" .)
