In the shrub, are without any cover (4)
I believe the answer is:
bare
'any cover' is the definition.
The answer and definition can be both to do with communicating as well as being verbs in their base form.
Perhaps you can see a link between them that I don't see?
'in the shrub are without' is the wordplay.
'in' indicates the answer is hidden within the clue.
'BARE' is hidden within 'shrub are without'.
Can you help me to learn more?
(Other definitions for bare that I've seen before include "Unadorned - naked" , "Stark - naked" , "Nude; uncover" , "Unclad" , "State of deciduous tree in winter" .)
