Buy a meat loaf stuffed with root vegetable (3)
I believe the answer is:
yam
'root vegetable' is the definition.
(yam is a kind of root vegetable)
'buy a meat loaf stuffed' is the wordplay.
'YAM' is hidden in amongst the letters.
However, I am unsure how the hidden word is indicated.
'with' is the link.
Can you help me to learn more?
(Other definitions for yam that I've seen before include "May be a sweet spud" , "May be a sweet potato" , "Tropical climber" , "Tropical root vegetable" , "May be a foreign potato" .)
