Very much aware that a veil is torn (5)
I believe the answer is:
alive
'very much aware' is the definition.
'alive' can be an answer for 'aware' (synonyms). I'm unsure of the 'very much' bit.
'a veil is torn' is the wordplay.
'is torn' is an anagram indicator.
'veil' with letters rearranged gives 'live'.
'a'+'live'='ALIVE'
'that' acts as a link.
Can you help me to learn more?
(Other definitions for alive that I've seen before include "Aware" , "surviving" , "answer, as it happens" , "Functioning" , "Extant" .)
