Amazed, saw broadcast about European lorry (9)
I believe the answer is:
awestruck
'amazed' is the definition.
(thesaurus)
'saw broadcast about european lorry' is the wordplay.
'broadcast' indicates an anagram (letters scattered or cast around).
'about' means one lot of letters goes inside another.
'european' becomes 'e' (abbreviation e.g. EU).
'lorry' becomes 'truck' (I've seen this before).
'saw' is an anagram of 'aws'.
'aws' placed around 'e' is 'awes'.
'awes'+'truck'='AWESTRUCK'
(Other definitions for awestruck that I've seen before include "Intimidated" , "full of admiration" , "Terrified" , "Filled with wonder" , "Suck water (anag) - completely astonished" .)
