US director supporting live puzzle (8)
I believe the answer is:
bewilder
'puzzle' is the definition.
(synonyms)
'us director supporting live' is the wordplay.
'us director' becomes 'wilder' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'supporting' says to put letters next to each other (in a down clue, some letters go below others).
'live' becomes 'be' (synonyms).
'wilder' after 'be' is 'BEWILDER'.
Can you help me to learn more?
(Other definitions for bewilder that I've seen before include "Perplex the wild beer" , "Flummox, confuse" , "Wild beer tending to confuse" , "Nonplus" , "Baffle" .)
