Given the chuck, had a restless night? (6)
I believe the answer is:
tossed
'given' is the definition.
The answer and definition can be both to do with contact as well as being past participle verbs.
Perhaps you can see an association between them that I can't see?
'chuck had a restless night?' is the wordplay.
'chuck' becomes 'toss' (synonyms).
'had' says to put letters next to each other.
'a restless night?' becomes 'ed' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'toss'+'ed'='TOSSED'
'the' is the link.
Can you help me to learn more?
(Other definitions for tossed that I've seen before include "Threw up, perhaps salad" , "Pitched" , "Threw up lightly" , "Christian festival" , "Threw casually" .)
