Most hulking of those transporting us to trial (8)
I believe the answer is:
stoutest
'most hulking of those' is the definition.
I can't tell whether this definition defines the answer.
'transporting us to trial' is the wordplay.
'transporting' indicates anagramming the letters (I've seen 'transported' mean this).
'trial' becomes 'test' (synonyms).
'us'+'to'='usto'
'usto' is an anagram of 'stou'.
'stou'+'test'='STOUTEST'
Can you help me to learn more?
(Other definitions for stoutest that I've seen before include "Most sturdy or fattest" , "Most corpulent - or most sturdy" , "Most solidly built or resolute" , "Most strong" , "Most enduring" .)
