Small container carried in trucks across country (3)
I believe the answer is:
sac
'small container' is the definition.
'sac' can be an answer for 'container'. I'm not sure about the 'small' bit.
'carried in trucks across country' is the wordplay.
'SAC' is hidden in amongst the letters.
However, I am not sure how the hidden word is indicated.
Can you help me to learn more?
(Other definitions for sac that I've seen before include "pocket" , "Bag, pouch; cyst" , "Bladder" , "Membranous cavity" , "Traditional entitlement to hold court" .)
