Nicaragua not blessed with mineral-rich deposits (5)
I believe the answer is:
guano
'mineral-rich deposits' is the definition.
I can't judge whether this definition defines the answer.
'nicaragua not blessed with' is the wordplay.
'with' indicates a hidden word.
'GUANO' is hidden in the letters of 'nicaragua not blessed'.
Can you help me to learn more?
(Other definitions for guano that I've seen before include "Bird droppings used as fertiliser" , "Manure from sea birds" , "Fertiliser from seabirds" , "Excrement of sea birds, used as fertilizer" , "Seabird excrement, once prized as fertiliser" .)
