Pass the time, maybe, when indisposed at the weekend (4)
I believe the answer is:
kill
'pass' is the definition.
(thesaurus)
'indisposed at the weekend' is the wordplay.
'indisposed' becomes 'ill' (similar in meaning).
'at' means one lot of letters go next to another (I've seen this in other clues).
'the weekend' becomes 'k' (I've seen this in other clues).
'ill' put after 'k' is 'KILL'.
'the time maybe when' is the link.
This may not be correct. Some or all of it may be part of another bit of the clue.
Can you help me to learn more?
(Other definitions for kill that I've seen before include "Slaughter" , "Put an end to" , "Deprive of life" , "Put to death" , "Cause to die" .)
