Herb has heard bird (5)
I believe the answer is:
thyme
This could be a double definition.
'herb' is the first definition.
(I know that thyme is a type of herb)
'heard bird' is the second definition.
The answer and definition can be both things that one consumes for nourishment as well as being singular nouns.
Maybe there's a link between them I don't understand?
'has' is the link.
Can you help me to learn more?
(Other definitions for thyme that I've seen before include "Shrub - herb" , "Sweet-smelling herb of the mint family" , "Strong herb" , "Kind of mint" , "Sage's bedmate" .)
