Caribbean runner? (4)
I believe the answer is:
bean
'caribbean runner?' is the definition.
The definition and answer can be both plants as well as being singular nouns.
Perhaps they are linked in a way I don't understand?
'caribbean runner?' is the wordplay.
'BEAN' is hidden in amongst the letters.
But, I am uncertain how the hidden word is indicated.
Can you help me to learn more?
(Other definitions for bean that I've seen before include "Vegetable; coffee seed" , "Seed of e.g. coffee" , "Kidney-shaped seed as for coffee" , "Seed of a leguminous plant" , "It's often baked" .)
