Pack of trained alpacas brought over and loaded (5)
I believe the answer is:
laden
'loaded' is the definition.
(I know that loaded can be written as laden)
'pack of trained alpacas brought over' is the wordplay.
'pack of' says the answer is hidden in the clue (I've seen 'packing' mean this).
'brought over' says the letters should be written backwards.
'nedal' is hidden within 'trained alpacas'.
'nedal' backwards is 'LADEN'.
'and' acts as a link.
(Other definitions for laden that I've seen before include "Like cargo boat" , "Like many a cargo ship" , "Eland (anag)" , "bearing burden" , "cargo aboard" .)
