Positive cry for help, being short of money? When will money arrive? (6)
I believe the answer is:
payday
'positive cry for help being short of money? when' is the definition.
I can't judge whether this definition defines the answer.
'money arrive?' is the wordplay.
'money' becomes 'pay' (I've seen this in other clues).
'arrive?' becomes 'day' (I can't justify this - if you can you should give a lot more credence to this answer).
'pay'+'day'='PAYDAY'
'will' acts as a link.
Can you help me to learn more?
(Other definitions for payday that I've seen before include "when wages are given" , "Time when wages are received" .)
