Nervous, shy (7)
I believe the answer is:
bashful
I believe this is a double definition.
'nervous' is the first definition.
(thesaurus)
'shy' is the second definition.
(I've seen this in another clue)
(Other definitions for bashful that I've seen before include "Sleepy companion" , "Shy, easily embarrassed" , "Shovel and pick worker" , "Dwarf" , "One of Disney's dwarves" .)
