Bolts when one laughs at (6)
I believe the answer is:
scoffs
'laughs at' is the definition.
The definition and answer can be both to do with communicating as well as being verbs in their -s form.
Maybe you can see an association between them that I can't see?
I cannot understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for scoffs that I've seen before include "Jeers or drinks up" , "Ridicules or eats slangily" , "'Jeers, scorns (6)'" , "Abandons diet" , "Laughs at the idea of" .)
