Nervous part of speech (5)
![Ross](/clue/static/ross-mug.min.png)
I believe the answer is:
tense
'nervous' is the definition.
(similar in meaning)
I can't explain the rest of the clue.
Can you help me to learn more?
(Other definitions for tense that I've seen before include "past, say" , "Taut - timely verbal indication" , "Worried" , "show strain" , "far from comfortable" .)
